These two are standard gcc libraries. You can ship them as binaries as long
you inform the user about their license and satisfy GPL requirements like availability of source code, etc.

Sometimes older/newer version is also good enough.
For example:
libgcc_s.so.1 from /usr/sfw/lib/ pre-installed on all Solaris 10 and 11 is usually satisfactory.
