no longer applies by modern FreeBSD patch(1). Patch was applied on the
FreeBSD 8.4 and new patches generated with ``make makepatch''. Repocopy
was waived since three-way split would make the diff unnecessarily noisy
and there's not much history to preserve anyways as the patch had not
been modified since its inception. While here, unbreak the build against
modern compilers (Clang 11, GCC 10) by forcing the `-fcommon' mode.
