I think the unwind routines can be found both in libgcc and in glibc.
However, I suspect they will only be in libgcc if gcc believes that the
linker supports the --eh-frame-hdr option.

Certainly the best way is to use a linker which supports --eh-frame-hdr
and use a gcc which believes that to be true.  Otherwise, you will need
to use gcc's startup code to register the exception frames.
