[Buildroot] [git commit] package/nvidia-driver: don't install gl.pc when not providing libgl

[Thomas Petazzoni]

commit: http://git.buildroot.net/buildroot/commit/?id=861cc84f8c7150d0578b8ec6189b4fec6c7d04e6
branch: http://git.buildroot.net/buildroot/commit/?id=refs/heads/master

When nvidia-driver does not provide libgl (i.e. when it does not install
the X.org driver), it should also not install gl.pc, otherwise, packages
that depend on pkg-config will mis-detect presence of GL and fail to
build, like vlc:

    http://autobuild.buildroot.org/results/724/724fce8ce51c2c0578192b1369a1cfcea3d72638/

So, only install gl.pc when we install the X.org driver. Similarly, we
do not need to install libGL.la either.
