Prevent make check from rebuilding GNU binaries over uutils ones

[ChrisDryden]

Fixes: #10907

My changes to not rebuild the Makefile appears to have caused the SELINUX Gnu tests to rebuild the gnu binaries and make the SELINUX gnu tests to use the gnu binaries instead of the uutils binaries.

GNU testsuite comparison:

Skip an intermittent issue tests/pr/bounded-memory (fails in this run but passes in the 'main' branch)
Skipping an intermittent issue tests/tail/symlink (passes in this run but fails in the 'main' branch)
Congrats! The gnu test tests/chcon/chcon is no longer failing!
Congrats! The gnu test tests/cp/no-ctx is no longer failing!
Congrats! The gnu test tests/date/date-locale-hour is no longer failing!

Interesting... why does GNU binaries not pass GNU tests?

For chcon we change the error message to include the binary, I believe its the same for no-ctx but I didn't investigate in depth
