>Description:
        In the usual mesa build, the gen_matypes program is run to
        generate gen_matypes.h prior to building assembler code.
        If this is not run, the build will fail spectacularly.
>How-To-Repeat:
        Attempt to build assembler code into libGL.
>Fix:
        see src/mesa/x86/Makefile for more details; basically, add
        gen_matypes.c to the build and dependencise so that it's
        run to create matypes.h for the right sources
