/* WORKAROUND pr80556:
For x86_64 Darwin10 and later, the unwinder is in libunwind (redirected
from libSystem). This doesn't use the keymgr (see keymgr.c) and therefore
the calls that libgcc makes to obtain the KEYMGR_GCC3_DW2_OBJ_LIST are not
updated to include new images, and might not even be valid for a single
image.
Therefore, for 64b exes at least, we must use the libunwind implementation,
even when static-libgcc is specified. We put libSystem first so that
unwinder symbols are satisfied from there. */
