Ideally you'd do a full buildworld/installworld here. On these machines
that takes a lot of time.

You may be able to do:

% cd lib/libgcc_s
% make clean obj depend all
% sudo make install

But that assumes your system has all the compilers, libraries etc installed
on it... If you are cross building, then just do a full buildworld since
the above depends on make includes and possibly other things running first.

If we still have armv6 snapshots, there's a chance that the
/lib/libgcc_s.so.1 from it will have the fix and you can copy it over...
but that might be more hassle and may be less safe than the above.

Good luck. And make backups of /lib/libgcc_s.so.1 before starting (keep a
copy in /lib, and use /rescue/sh if you mess this up and /bin/sh can't run
for single-user).
