Usertag: arm64
emacs23 does not build on arm64. The package was lacking support
for the arch. The attached patch adds that support, but the build
still fails. It hangs apparently forever (left for several hours
at 100% cpu) at this point (log shows eventual interrupt):

There may be something wrong with src/m/aarch64.h which is causing
this problem, but it's not obvious what. emacs24 builds OK, but
seems to have removed this special per-arch config.
I'm filing this bug in case the maintainers have any clue what the
issue might be and so that those of us working on the port can
compare notes. Hopefully someone can improve on this patch.
emacs23 is important because 'emacs' depends on it, and thus
various packages are uninstallable, and this is causing a lot of
builds to fail. If 'emacs' were to move on to emacs24 the FTBFS
would become much less significant. Ubuntu and fedora have already
moved over. Is there any reason why we should not do so?
