[PATCH 0/4] Makefile/perl: correctly re-generate build/* + speed up under NO_GETTEXT=Y

These patches are relatively trivial fixes for bugs noticed when I was working on recent send-email patches. We don't re-build perl/build/* assets when variables that affect them are changed, and needlessly use our non-mock gettext Perl i18n framework under NO_GETTEXT=Y if the system happens to have Locale::Messages installed.

Ævar Arnfjörð Bjarmason (4):
  Makefile: don't re-define PERL_DEFINES
  Makefile: regenerate perl/build/* if GIT-PERL-DEFINES changes
  Makefile: regenerate *.pm on NO_PERL_CPAN_FALLBACKS change
  perl: use mock i18n functions under NO_GETTEXT=Y
