The problem is that <functional> is included (via <map>) after abort has been
defined as a macro to fancy_abort. And thus when the C++ standard headers try
to call std::abort, they end up calling std::fancy_abort, which of course
doesn't exist.
A simple fix is to include <map> in gcc/config.h before we mess with abort.
