This prevents failures like "libgcc_s.so.1 must be installed for pthread_cancel to work" that occur because Glibc assumes libgcc_s.so.1 to be in Glibc's libdir. This solution is pretty hacky, because the libgcc_s.so.1 from bootstrap-tools might be too old. So if we update GCC, programs might end up using an outdated libgcc_s.so.1. Ideally, we would build libgcc_s.so.1 *before* Glibc, which might not be impossible... Fixes #3548.
