Since glslang 14.0.0, OGLCompiler and HLSL stub libraries have been
fully removed from the build.
This fixes the configuration by detecting if the stub libraries are
still present (glslang releases before version 14.0.0).
ffbuild/config.log:
/usr/lib/gcc/x86_64-pc-linux-gnu/13/../../../../x86_64-pc-linux-gnu/bin/ld:
cannot find -lOSDependent: No such file or directory
/usr/lib/gcc/x86_64-pc-linux-gnu/13/../../../../x86_64-pc-linux-gnu/bin/ld:

/usr/lib/gcc/x86_64-pc-linux-gnu/13/../../../../x86_64-pc-linux-gnu/bin/ld:
