arch_libdir was brought in to improve the heuristic determination of
the lib/ directory based on arch and testdir names, but it did not
entirely clean that mess up.

Remove the arch_libdir->arch->testdir heuristic and just require
everybody sets arch_libdir correctly. Fail if the lib/arch or
lib/arch/asm directories can not be found.

FYI, this patch seems to trigger yet another issue with Clang (I used v21):
