[Tfug] Beware of xorg-x11-7.1

[erich]

     This package brakes video games and the like. This package
includes the library, libGL.so.1.2

     I installed it on one of my machines and got:

      mythbackend: error while loading shared libraries: libGL.so.1:
      cannot handle TLS data

where libGL.so.1 points to libGL.so.1.2.

     Fortunately I had NOT upgraded on my other machine which has
xorg-x11-6.8.2-r7. When I copied it's repective libGL.so.1.2 to
my ailing machine the problem went away. This problem is exactly
reproduceable. TLS: Thread Local Storage.

     There are directory size differences:

  -rwxr-xr-x  1 root root 391352 Jun 21 22:23 libGL.so.1.2.new
  -rw-r--r--  1 root root 543215 Jun 21 22:27 libGL.so.1.2.old
