It is currently not possible to do a full MariaDB build without touching the
source tree, i.e. such that the the source tree could exist on a read-only
filesystem. This columnstore build file currently creates temporary files in
the source tree to evaluate how the operating system handles them, so it is
one blocker to these isolated builds.
This patch adjusts these tests to create the temporary files in the output
directory, rather than in the source tree.

On AMD64 machines, the fpu is 80 bits. The unused bits must be masked for memcmp to work properly. For other archetectures, we don't want to mask those bits.
