If you allocate anywhere near this, like 1 GB for example,
you'd be better off with 64-bit. Address space allocations
go slower when your address space is getting fragmented
and full. They might even fail from fragmentation.

c) handle large files using the traditional API
d) efficiently do math on large numbers, either directly
with "long long" or with a bignum lib
e) not have two C libraries resident in memory

Huh? OK, in "install" itself, it's a pain in the ass.
For all the other apps (count SourceForge projects alone)
a pain-in-the-ass support issue goes away.
Prior to /lib64, the most arch-specific thing in my Makefile
was a "-fpic" that half the ports don't need. It was all
clean and simple: no "./configure", no libtool, no auto*,
and no shell hacks.

If having a 32-bit build machine is not practical,
then a chroot() environment can be used for 32-bit
builds. It's cross-compiling for a different arch.
(while procps does fully support cross-compiling
by setting variables on the "make" command line,
you'd better do a chroot when dealing with many
thousands of different packages)
