A problem I've found is that Mesa's gen_matypes tool is not suitable for 
cross-compilation. It computes offsets into structs on the build platform, 
but the structs don't use fixed-size types for the members. So on a 64 bit 
platform the header file the tool generates contains offsets that can't 
work on a 32 bit Haiku.

The build system already has a mechanism to generate headers with struct 
offset definitions. It should be possible to use it here, too.
