gcc: Fix build on musl with -fstack-protector
When enabling the secutity flags on musl based targets the builds fail
due to libssp(gcc-runtime) build asking to link with libssp and
libssp_nonshared.a when configuring libssp itself. This does not work
with musl since it does provide ssp implementation but not like glibc
where these libraries are separate to libc
Fix the nios2 patch with upstream status while at it and generate the
patch after applying to my tree
