coreos/config: add fix for perl cross-compilation

Browse Source 
Current cross builds of perl segfault on simple operations such as `perl -V`.
This appears to be due to the cross-build not getting `-fwrapv -fno-strict-aliasing`
passed from the configure script. While we try to get this fixed upstream, we
can monkeypatch our old version of perl to fix this.
