+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
