So should this work now that we have the portable dumper?

Yes, 64 bits works on AIX now, due to the portable dumper (I hacked on that a bit last year to get it to work on AIX). I double-checked just now by building on AIX 7.1 via:

export OBJECT_MODE=64 # not sure this is needed
mkdir build
cd build
../emacs-27.1/configure CC='gcc -maix64' --with-jpeg=ifavailable --with-png=ifavailable --with-gif=ifavailable --with-tiff=ifavailable --with-gnutls=ifavailable

This was with GCC 4.8.1 (in /opt/freeware/bin/gcc).

There were some compile-time warnings, all bogus that I could see, and I could run Emacs just fine after the build. The command 'file src/emacs' reports:

src/emacs: 64-bit XCOFF executable or object module not stripped

Since the 64-bit build is working on AIX 7.1 now, I'm closing the bug report.
