libffi @3.4.8: doesn't build for x86_64 on Apple Silicon

[Zabolekar (Stanislav Syekirin)]

On Apple silicon with build_arch set to x86_64, some ports, notably libffi, don't build.

To reproduce:

git clone https://github.com/macports/macports-base.git
cd macports-base
git switch --detach v2.11.6
./configure --prefix=/opt/bug
make
sudo make install
sudo /opt/bug/bin/port selfupdate

Then edit /opt/bug/etc/macports/macports.conf and uncomment build_arch x86_64.

Then try running sudo /opt/bug/bin/port install libffi.

Output:

Error: Failed to build libffi: command execution failed
Error: See /opt/bug/var/macports/logs/_opt_bug_var_macports_sources_rsync.macports.org_macports_release_tarballs_ports_devel_libffi/libffi/main.log for details.
Error: Follow https://guide.macports.org/#project.tickets if you believe there is a bug.
Error: Processing of port libffi failed

Attachments: main.log.

My current workaround is to comment the build_arch, build libffi with +universal, then uncomment the build_arch again and proceed with building ports that depend on libffi.
