Currently the SML/NJ runtime is only available as a 32-bit program.

The SML/NJ compiler does support generating 64-bit binaries, but they
can't be run until upstream has completed work on the 64-bit runtime as
well. Therefore ...

... this flag is still essential for making SML/NJ run on amd64.

The missing assembler flag (--32) is indeed the problem with FreeBSD 12
on amd64. Using a seperate ASFLAGS variable in the port's Makefile and
passing it through the SML/NJ makefiles in base/runtime/objs fixes the
issue for me on 12-STABLE amd64. Please try the following patch:

        <ftp://offshore.free.de/pub/patch/smlnj.patch.20181220>
        MD5 (smlnj.patch.20181220) = a9067eb9a8b19d9ca6ff04911825ae62

This patch also updates lang/smlnj to the latest upstream version
110.84, which saves me some work compared to having a seperate fix for
the old version 110.77.

Please let me know if this patch also works for you. Then I'll give it
some more testing here (incl. 12-STABLE on i386) and suggest it to
be commited to the ports tree if all goes well.

Thanks!
Johannes
