Compiling on Gentoo

[iegor]

Hi there,

I have trouble with compiling on Gentoo, I will probably do a fork and just fix this but also want to share.

Looks like the _mesa_error_no_memory function is defined in
src/glsl/main.cpp and in
src/glsl/standalone_scaffolding.cpp
and that causes an error while linking.

Same issue on Arch x64.

See commit e480701 of open PR #91.

And / or see diff in this issue on the zz85 fork (omit the hacks in glsl_optimizer.cpp) for this and another linux build issue and merge #104 to resolve segfaults / hangs in release builds.
