>Description:
MD_FALLBACK_FRAME_STATE_FOR wants to be able to unwind
the stack through signal frames, so it uses <signal.h> and <sys/ucontext.h>
to find the sigcontext's members.  If you do not have a libc for your target, libgcc can not be compiled, because those headers are not found.

It's easy to work around this by adding #ifndef inhibit_libc, but the compiled
copies are included in a glibc built with that compiler (currently), and
so stick around.  I should not have to rebuild glibc a second time just to get
this correct.  Would hardcoding the necessary offsets or structures be an
acceptable alternative to including the header files?  If so, I can make a patch.
