(svn r3267) -Codechange: [OSX] universal binary makefile code cleanup
now PPC code is always compiled before x86 code
strgen and lng files are only compiled once, which results in shorter building time
the makefile now assigns default values to undefined values so much less needs to be set up
the code is now easier to maintain

# Usage
#

# Synopsis:
#
# make WITH_ZLIB=1 UNIX=1 MANUAL_CONFIG=1
#
# (See below for the list of possible options.)
#
# Alternately, you can run make without the MANUAL_CONFIG part. It then
# generates Makefile.config, where you can customize all the options.
# However beware that for all subsequent calls the option values from
# Makefile.config take precedence to the commandline options.
#
# (That means that you probably want to either specify the options on command
# line together with MANUAL_CONFIG=1 or you want to specify no commandline
# options at all.)

# Targets:
#
# Defaults to building binary
# clean: remove intermediate build files
# mrproper: remove intermediate files and makefile configuration
# upgradeconf: add new options to old Makefile.config
# osx: OS X application
# release: used by OSX to make a dmg file ready to release

# Options:
#
# Summary of OS choice defines
# WIN32: building on Windows
# UNIX: building on *nix derivate (Linux, FreeBSD)
# OSX: building on Mac OS X
# MORPHOS: building on MorphOS
# BEOS: building on BeOS
# SUNOS: building on SunOS (Solaris)
#
# Summary of library choice defines
# WITH_ZLIB: savegames using zlib
# WITH_PNG: screenshots using PNG
# WITH_SDL: SDL video driver support
#
# Summary of other defines:
# MANUAL_CONFIG: do not use Makefile.config, config options set manually
# DEBUG: build in debug mode
# PROFILE: build in profile mode, disables -s and -fomit-frame-pointer
# TRANSLATOR: build in translator mode (untranslated strings are prepended by
#             a <TODO> mark)
# RELEASE: this will be the released version number. It replaces all places
#          where it normally would print the revision number
# MIDI: if set, it will use it as custom path to midi player.
#       If unset, it will use the hardcoded path in the c code
#       This can still be overriden by the music.extmidi openttd.cfg option.
# WITH_DIRECTMUSIC: enable DirectMusic MIDI support
# WITH_NETWORK: enable networking
# DEDICATED: allows compilation on UNIX without SDL. Useful for dedicated servers
# MAX_NUM_AUTOSAVES: sets the number of autosaves the games will make before starting
#		to overwrite the old ones. If not set, the game will use 16.
#		NOTE: assign a number, not a string of a number
#
# Paths:
# INSTALL: If not set, the game uses the directory of the binary to
# store everything (lang, data, gm, save and openttd.cfg), this is the `old' behaviour.
# In this case, none of the following paths are used, you also should _not_
# use `make install', but copy the required stuff yourself (or just play out
# of you source directory, which should work fine).
# If you want to use `make install' to install the game globally, you should
# define it _before_ you build the game. If you only define INSTALL when you
# do `make install', the game won't be able to find it's files (so you should
# also define all the following paths before building).
#
# So, the following paths should be defined if INSTALL is defined.
# None of these paths have to end with /
# PREFIX:	Normally /usr/local
# BINARY_DIR:	The location of the binary, normally games. (Will be prefixed
#		with $PREFIX)
# DATA_DIR: 	The location of the data (lang, data, gm and scenario), normally
#		share/games/openttd. (Will be prefixed with $PREFIX) Note that scenarios
#		are only put here if USE_HOMEDIR is true, otherwise they are placed in
#		PERSONAL_DIR/scenario
# PERSONAL_DIR:	The directory where openttd.cfg and the save folder will be
#		stored. You cannot use ~ here, define USE_HOMEDIR for that.
# USE_HOMEDIR:	If this variable is set, PERSONAL_DIR will be prefixed with
#		~/ at runtime (the user's homedir)
# SECOND_DATA_PATH  Use this data dir if a file is not found in the data dir in the data path
# CUSTOM_LANG_PATH  If this is set, it will use the path given to search for lng files
#		instead of the lang dir in the data path
#   NOTE: both SECOND_DATA_PATH and CUSTOM_LANG_PATH uses paths relative to where OTTD is opened
#
# DEST_DIR:	make install will use this directory instead of the filesystem
# 		root to install its files. This should normally not be used by
# 		ordinary users, currently it is only used for the debian
# 		packaging. This value should only be set when calling `make
# 		install' and is not saved in Makefile.config
#               (Note that DESTDIR is checked if DEST_DIR is not set.)
#
# STATIC: link statically
# CYGWIN: build in Cygwin environment
# MINGW: build with MingW compiler, link with MingW libraries
#
# VERBOSE: show full compiler invocations instead of brief progress messages
#
# Special for crosscompiling there are some commands available:
#
# BUILD_UNIVERSAL_BINARY: builds a universal binary for OSX. Make sure you got both PPC and x86 libs
#
# ENDIAN_FORCE: forces the endian-check to give a certain result. Can be BE, LE or PREPROCESSOR.
#	PREPROCESSOR is always used on all OSX targets and will make the preprocessor pick the right endian.
#	this means that you don't have to think about endianess when compiling for OSX.
#	Very useful for universal binaries and crosscompilers. Not sure if it works on non OSX targets
# WINDRES: the location of your windres
# CC_HOST: the gcc of your localhost if you are making a target that produces incompatible executables
# CFLAGS_HOST: cflags used for CC_HOST. Make it something if you are getting errors when you try to compi
#		windows executables on linux. (just: CFLAGS_HOST:='-I' or something)
