[LTP] NUMA tests not suitable for cross-compilation

[Carmelo A. <car...@st...>]

Hi,
the test on NUMA machine is done at build time on the host (the build 
machine)
on the number of files in the /sys/devices/system/node directory:


x=$(ls /sys/devices/system/node | wc -l)
if [ $x -gt 1 ]
then
echo yes; # numa is available
else
echo no; #numa is not present
fi

When doing cross-compilation this doesn't make sense.
We can easily comment out the whole directory from the build system.

Anyway, to address this kind of issues, I think it could be useful to add
a sort of .config option to the LTP build system, or something else similar.

Also latest fix to check if /usr/include/numa.h is present, works only
if host and target machine are the same (using same kernel), while
doesn't make sense in cross-compilation.

Regards,
Carmelo
