Use -no-undefined libtool flag in src/glx/Makefile.am
"Use -no-undefined to assure libtool that the library has no unresolved
symbols at link time, so that libtool will build a shared library on
platforms that require that all symbols are resolved when the library is linked."

glx: Fix glXGetProcAddress() of global glX symbols post-automake conversion.
When a GL LD_PRELOAD library like apitrace was used,
glXGetProcAddress() would return the preload's symbols instead of
libGL's symbol, leading to infinite recursion when the returned
function was called. This didn't hit apitrace on most apps because
who calls glXGetProcAddress() on the global functions.
The -Bsymbolic, which was present in mklib before automake conversion,
causes the glxcmds.c:GLX_functions table to be resolved at link time,
so that LD_PRELOADs don't affect it any more.
Fixes crashes when running wine under apitrace.

This fixes a build problem where EGL links to libgbm.la, which encodes
a relative path to it's libglapi.so dependency. The relative path
breaks when the linker tries to resolve it from src/egl/main instead
of src/gbm. Typically we silently fall back to the system
libglapi.so, which is wrong and breaks when there isn't one.
Morale of the story: don't mix mklib and libtool.
glx: Also put a symlink from libGL.so in lib/ for now.
This fixes the libGLU.so.* build when a system libGL.so is not present
since it is relying on the lib/ to build against until it gets
converted to automake.
