backout the gethunk() again, as that breaks the assemblers

the assemblers share gethunk() cc/macbody but are compiled
without compat.c, so calls such as getenv() trigger malloc()
which does its own sbrk() calls, breaking the continuity
of the hunk.

so this change needs another revision. until then, this is
backed out.
