The mcount.po target is special cased here since mcount.c should not be compiled with pie or profiling enabled. This was missed when the independent depend target was removed. Align this target with the inference rules in bsd.lib.mk. This now creates mcount.d as it should and fixes 'make clean' which previously left mcount.po.d behind.

This thread-aware profiling support diff comes from Yuichiro NAITO. At runtime, profiling data is stored per-thread. Upon termination, the per-thread profiling data pools are merged into a into a single record, which is then written out (using the new kernel-assisted system). I think the original gmon merging parts may have come from or been inspired by someone at NetBSD. This has been delayed because there were concerns about adding a TLS object which would require other library cranks, so this rides all the major cranks today. ok kettenis tb claudio sthen etc etc etc
