Not so straight forward (esp. if you use linked in drivers as we do). 
Here is what it takes

First this patch:
This patch allows 64-bit builds when the target system supports both
32-bit and 64-bit in the same system environment.  Specifically, this
works on Solaris 10/Opensolaris, and adjusts the --enable-darwin-64-bit
configure flag to be simply --enable-64bit so that it can be used for
the same purpose on both darwin and solaris (building 64-bit target
environment) without having to introduce another system specific
configure flag.

This cleanly builds with the following configure command line:

~/bld/otp_src_R12B-3$ CFLAGS='-m64' LDFLAGS='-m64' ./configure \ 
--enable-threads \
--enable-smp-support --enable-kernel-poll --enable-hipe \
--disable-megaco-flex-scanner-drvlineno --without-odbc \
--enable-64bit

on:

~/bld/otp_src_R12B-3$ uname -a
SunOS pfisher-laptop 5.11 snv_94 i86pc i386 i86pc Solaris

This does not fix common_test, which seems to be in its own world, and
I'll send another patch for that.  For now I just set it to SKIP.
