Subject: [PATCH] Do not check for libGL symbols when checking libOSMesa
If mesa had been built with shared glapi, glAccum is not available in
libOSMesa without explicitly linking to libGL. In addition, in
mesa-8.0.x and earlier, libOSMesa needs to be explicitly linked to
libglapi if mesa was built with shared glapi, see
https://bugs.gentoo.org/show_bug.cgi?id=399813
And in mesa-8.1.x, libOSMesa in addition needs libdl, libpthread, and
libstdc++, see https://bugs.gentoo.org/show_bug.cgi?id=431832
