I think these changes are very likely to be 100% correct, as not having
them fails to bootstrap too many times.  Their intent was to only use
posix_memalign() when the system's malloc() is used.  Otherwise we risk
having a memory area allocated by posix_memalign() and then freed with
Emacs' internal gmalloc or vice versa.

With these changes, on the other hand, failures during bootstrapping on
FreeBSD/amd64 have stopped immediately here :-)
