ltp: Fixing determinism issues
Add a patch adding sorting to a couple of points in the Makefiles
which removes most of the determinism issues in ltp.
Build swapon before the main build to ensure libswapon.o is built
deterministically as it races with swapoff.
All issues reported on the upstream mailing list.
(From OE-Core rev: 0f51f9a37e5d058bce28cfe7b9a32a895f83c091)

3 | Currently the list of tests is generated by the order of the files found | ||
4 | within the directories. This results in differences in the run.sh and | ||
5 | Makefiles. Within Yocto Project this results in differing target | ||
6 | test packages. The fix is simple, just sort the output from locate-test. | ||

14 | Sort the wildcard expansion of *.c which leads to reproducible binaries. | ||
