Link against libgcc and libc to avoid unresolved symbols

We need to link agaisnt -lgcc, on at least hppa. We also need to link
against -lc, because we are now always using the syscall() libc function.
So let's stop passing -nostdlib and -nostartfiles.

Note: we used to use -Wl,--as-needed, this way we made sure we pulled the
required fortified functions from the internal libc_nonshared.a, but did
not link against the shared library because we did not use any of its
symbols.
