I'm not sure why this would not have shown up before but the FreeBSD kernel
reuses some standard library method names with different signatures. The
file rtemsbsd/include/machine/rtems-bsd-kernel-namespace.h renames a lot of
items to put them in a BSD namespace. qsort_r isn't in this list but
perhaps should be.
