Working on this now, a better patch should be hitting the ML soon.

This new patch has some cleanup as well and should represent everything 
major we
need to get mesa working on Haiku.

In the upcoming patch, we are building several static libraries.. this 
is expected.

The plan for Haiku is that we will have a script within the Haiku 
project which
handles extracting what we need from Mesa.

This script will...

1) Build mesa for haiku via 'make haiku'
2) Zip up:
     - All of the mesa headers we use within our openGL kit which wraps 
libGL, and
       dependencies on those headers found via gcc -MM
     - All the .a static libraries.
3) During the Haiku build process, we pull the zip above and expand it 
within our
build directory.  We then take the static libraries and link them all 
into libGL.so.

This should cover us for software rendering. I've successfully compiled 
several
Gallium3D drivers, however getting stock Mesa into the build system is 
definitely
my first goal.

Thanks!
