Linux/PPC Segfault in Build

get Parrot to build. Here's the relevant message:

Going into compilers/pge and massaging the Makefile not to delete the
appropriate files gets me further. Now TGE has similar problems, and I get
back to:

It looks like the latest coroutine changes have uncovered a bug; now I can't
get Parrot to build. Here's the relevant message:
It's actually something I introduced (in continuation changes; coroutine
changes are still yet to come). r14845 should correct it. Sorry for
the hassle.

Confirmed fixed! Thanks.
