So! We now have a working external Mesa3D running under gcc2 without
any Mesa patches thanks to the hard work of mmlr.

mmlr figured out a way to put the gcc4 compiled mesa into the gcc2
haiku build process and come out with a libGL.so consisting of:
<Haiku gcc2 opengl kit> + <Mesa gcc4 binaries> + <haiku gcc4 libstd +
libstdc++>
This process works for gcc2 builds. You can try it here:
http://pub.haikufire.com/mesa/haiku-mesa-gcc2.image.gz
Here is the general process:
- We build a gcc4 mesa optional package
- We extract c++ symbols that the haiku build gcc2 linking was
complaining about from the gcc4 libstd + libstdc++ and create a mini
gcc4 standard static library.
- During the gcc2 image build we link in the mini gcc4 standard
libraries from the optional package (around 500KB extra).
One pitfall of this is we are seeing
http://dev.haiku-os.org/ticket/7785 when we try to run the OpenCL
preference pane under gcc2. GLTeapot seems to work just fine however.
In essence we only need one mesa optional package per architecture.
I am working through automating mmlr's black magic in the Mesa build
script and hope to have something polished soon.
Thanks! (and thanks to mmlr for the idea and figuring out how to do it!!)
