Yeah, that's actually what we do. After configure, but before make,
we:
cat configs/autoconf | sed -e "s,GL_LIB = GL,GL_LIB=MesaGL,g" > \
configs/autoconf.edit || return 1
mv configs/autoconf.edit configs/autoconf
cat configs/autoconf | sed -e "s,GLU_LIB = GLU,GLU_LIB=MesaGLU,g" > \
configs/autoconf.edit || return 1
mv configs/autoconf.edit configs/autoconf
The crazy way of doing it (i.e. not sed -i) is because AIX's sed is
garbage.
Anyway, the build does seem to know about this, AFAICT; we do it this
way specifically so that the gl.pc file will contain "-lMesaGL", i.e.
the correct library name.

Well, I would expect the symbol would be present but just not exported,
right? i.e. a lowercase `t' in nm instead of an uppercase one.
