The former has build system issues, with missing Kyuafiles, presumably
due to not using TESTS_SUBDIRS and bsd.test.mk (and possibly some issues
on top of that around TESTSDIR and related variables). The latter has
issues with GCC and cut-down LLVM builds.

Fixes: ccb59683b9 ("arm64: add tests for swp/swpb emulation")
One test is suitable to be hooked up to the build, so I've done this
here. The other test lives in tools/regression because failure is a
bit more subjective -- generally, one runs it for some unbounded amount
of time and observe if it eventually exits because two threads acquired
the same mutex.
