No luck building GCC on sparc-linux using --with-gc=zone

It should work for any target with mmap I think.  However, it is fairly 
new, so it may still have some portability problems.

The default is for gcc to not dump core when it ICEs.  Core files just 
confuse average users.  We only generate a core file if we have an 
unhandled signal that causes a core dump.  To debug the problem, you 
need to run cc1 (or cc1plus or whatever) under gdb, and put a breakpoint 
on fancy_abort.  The gcc .gdbinit file will do this for you 
automatically if you run gdb in the build tree.
