Two comments...

First, it appears that autobuild's argument parsing is sensitive to options
before vs. after the subcommand. I always use "autobuild build -A 64",
which works. I don't know why it doesn't work equally well the other way,
but yours is not the first time I've seen a similar complaint.

Second, I'm glad that the fmodex build responded well to the override. Just
last week I had to tweak the build-cmd.sh scripts for both jsoncpp and
breakpad because their build systems were not forwarding the architecture
or address size properly, and the "darwin64" build was still producing
32-bit libraries. I'm not yet convinced that we've seen the last of that
issue; just be aware that that might be the cause of observed problems.
