libsys/arm: include ARM EABI unwind bits into libsys

libsys required ARM EABI unwind symbols like __aeabi_unwind_cpp_pr0.
These symbols are normally provided by libc, but if a binary does
not link libc, the symbol ends up not being resolved.

Among other problems, this prevented gcc14 and newer from building
on arm.

Add the relevant symbols as hidden symbols into libsys to avoid this
problem.

(this patch was posted by jrtc27 who has asked me to move it along)

powerpcspe/Makefile.sys's structure means it had to be modified when moved
so rename detection won't work, but it has trivial contents so the
history is unimportant.
