Bug#696757: ecl hang: SIGNAL problem

Hi all!
I guess ecl has never ever worked with libgc and enabled threads on
kfreebsd (seems to be a header-only thing and libgc added thread support
for kfreebsd *after* the last successfull ecl build).
It still seems to be waiting in GC_stop_world() for all other processes
to finish and probably the issue is asynchronous_signal_servicing_thread
(the function the non-eglibc non stopping thread is in)
not correctly responding to SIG_SUSPEND (the signal sent in
GC_stop_world)
I guess we can back out the threads patch from libgc. If any of you can
figure out how to fix that thing that'd be an option as well.
