configure: Add configure options to override the GL library name 

This adds 3 configure options to override the library name that gets
dlopened for GL, GLES and GLESv2. This could be useful for distro
maintainers who have an unusual name for the libraries (for example,
on OpenBSD the GL library appears to be called libGL.so.4). This could
at least be simpler than having to create a distro patch.

The configure options would be used like this:

./configure --with-gl-libname=libGL.so \
            --with-gles1-libname=libGLESv1.so \
            --with-gles2-libname=libGLESv2.so
