Add support for "platform" configurations, which define a suite of compiler-rt libraries to generate. - Each library may be built with different flags and for different architectures, and there is support for building Darwin style fat archives. - Uses an ambituous amount of make programming, but should be hidden to users and developers. llvm-svn: 93720 2010-01-18 14:49:33 +08:00			`Description := Example configuration for build two libraries for separate \`

Add a VISIBILITY_HIDDEN option, which can be used to make all compiler-rt function definitions hidden/private extern. llvm-svn: 93790 2010-01-19 06:19:34 +08:00			`FUNCTIONS.m64 := $(FUNCTIONS) lshrdi3`
