XviD @1.3.7+universal: parse failure with arm64 in universal_archs

[ShadSterling (Shad Sterling)]

port info XviD, port clean XviD, port variants XviD, and port install XviD have the same output:

Error: Unable to open port: can't read "my_targets(arm64)": no such element in array

Since these commands work as expected with other ports I suspect the problem is with the port, but it seems pretty amazing that info doesn't work

I have +universal in my /opt/local/etc/macports/variants.conf. I don't use XviD, this came up as a failure in port clean all

Output of port -d clean --all -f XviD:

xvid needs to either handle target(arm64) or mark it as unsupported on arm64.

It builds fine on arm64 when not using the universal variant.

In faa70a86d2fa7b7b0c53a61b827061c5f6ea0270/macports-ports (master):

XviD: Fix universal build that includes arm64

Closes: #63146

Also presumably fix ppc/i386 universal build by ensuring that
--disable-assembly is specified for the Intel parts and not the PowerPC
parts regardless whether the build machine is Intel or PowerPC.

See: #32802
