Pushing out a fix for a really annoying hang, resulting from a grep that fails after the first switch (#55120). Thanks to Michael Sterrett <mr_bones_@gentoo.org>.

+       This utility switches between OpenGL implementations.  Currently there
+       are five supported implementations, "xorg-x11" "xfree" "nvidia" "ati"
+       and "mtx", the implementations for X.org, XFree86, nVidia, ATi
+       and Matrox drivers respectively.
+
+examples:
+       ${0##*/} xorg-x11
+       This will setup things to use libGL.so from X.org.
+
+       ${0##*/} nvidia
+       This will setup things to use libGL.so from the nVidia drivers.
