for x86 and evbarm:
- install headers and libEGL
- install xorg-server glamoregl component
- link xorg drivers against gbm/egl
bonus fix:
- fix some wrongly marked compatx11file files
build tested on shark, sgimips, evbarm64-el, amd64 and i386.
run tested on radeon, intel and nvidia on amd64, including
'modesetting' driver on amd64. however, my systems disable
it due to llvmpipe so i'm not sure what is happening.
- add khrplatform.h for mesa_ver=18 platforms.
need to enable libvdpau.pc generation (needs special rules)
this mostly comes from maya in the first one, and a small part
of the second:

Adjust for MesaLib 18.
Build llvmpipe driver on x86 (the driver itself is x86-only).
build llvm on all x86, even on GCC builds.
galahad driver removed (upstream).
Don't build mesa 7 at all.
