mesa: added #ifdef __GNUC__ around GLubyte bitfield usage

It would be nice if there were a #pragma or something to disable the warnings:

main/texenvprogram.c:87: warning: type of bit-field ‘Source’ is a GCC extension
main/texenvprogram.c:88: warning: type of bit-field ‘Operand’ is a GCC extension

but there doesn't appear to be a way to do that.
