patch under test

this is what I'm testing
 - these functions are removed from libgcc.a and added to libgcc_eh.a
 - since most versions of Darwin cannot use libgcc_eh, it arranges to make a
CRT containing them that can be linked in cases that require it.
 - for Darwin, we also make the definitions weak and exported where used in
DSOs, this means that a dynamically linked program should only end up with =
one
copy of the cache even if the shared libgcc is not in use.=
