Description of problem:
mesa-source contains unconditional selinux references, esp in main/execmem.c

Version-Release number of selected component (if applicable):
mesa-source-7.0.1-7

How reproducible:
Always

Steps to Reproduce:
1. try to compile xorg-servers without selinux
  
Actual results:
execmem.c contains unconditional selinux code (hauled in from mesa package).

Expected results:
meas should not have unconditional selinux code

Additional info:
The question is: should successful compilation of xorg-servers without selinux
be dependent on mesa build without selinux? Probably not.
One fix would be for mesa code to surround the selinux stuff with:
#if defined(WITH_SELINUX) || defined(USE_SELINUX) || defined(WITH_LIBSELINUX)
which would cover most cases (but it is alarming that there is such a variety of
conditionals for selinux ... goodness knows why autoconf stuff doesn't use a
more modular approach - like standard chunks of configure.ac to include).
The other solution would be for xorg-servers to link with a pre-compiled mesa
library which is the normal way to do things (rather than copy the mesa source
code).
