Link against libgcc and libc to avoid unresolved symbols

Link against libgcc and libc to avoid unresolved symbols

We need to link agaisnt -lgcc, on at least hppa.

We also link against -lc and -Wl,--as-needed, this way we pull the
required fortified functions from the internal libc_nonshared.a, but
do not link against the shared library because we do not use any of
its symbols.
