Ian changed that in bf9850db to kludge around some kind of linker errors
he was getting.  It's entirely wrong.  glsl_compiler links with
libglsl.a, which includes builtin_function.o.  So there's no reason at
all for it to luse builtin_stubs.o (which is _only_ meant for

Removing it seems to work fine here...for the moment.  But I do remember
seeing it break the build on his system.  No idea why.  I guess I should
try it on Fedora sometime.

Yeah, absolutely.
