graphics/libGL and graphics/libGLU broken with ARCH=i386

[Dominic Fandrey]

First of all, both ports don't obey my CC/CXX settings (I use ccache).

I'm trying to cross-compile for i386 setting ARCH=i386. Building 
graphics/libGL complains about assembler errors. This can be fixed by adding 
-m32 to the CFLAGS.

The graphics/libGLU port is a tougher cookie. I have set LOCALBASE to 
/usr/local32, however the port shows abominations like 
-I/usr/local3232/include while compiling.

I have worked around this by adding -I/usr/local32/include to CFLAGS, but 
there are problems I don't know how to solve:
