[Mesa-dev] Mesa (master): glsl: Autogenerate builtin_functions.cpp as part of the build process.

[José Fonseca]

I've fixed the getopt.h  dependency and talloc linking. MSVC is now
building without errors.

MinGW cross-compilation is still broken because a different compiler
must be used for builtin_functions (ordinary gcc instead of
i586-mingw32msvc-gcc)

This was also necessary for Michal's glsl frontend, so I'll bring back
the scons glue from that time.
