Upgrading libc isn't safe in general, without recompiling everything
that depends on it. In this case it looks like libHSrts.a has captured
some inline code from the old header files, which refers to things which
don't exist in the new libc. Even if you still have the old libc
installed, it still doesn't work because -lc tends to pick the latest
version.
