I've been trying to duplicate the macintel builds from the meta/build system on
mac 10.6 system with 64-bit kernel (uname -m => x86_64).
So in a git plt tree...
../src/configure --enable-sdk=/Developer/SDKs/MacOSX10.4u.sdk
make both
fails with...

It appears that the problem centers around the
if test `${UNAME} -m` = "i386" ; then
in the configure script and hacking out this test allows for the build to
complete.

This is only meant to be illustrative since the real fix needs to be in
configure.ac and likely there was a reason for this check so removal may not be
an option.
Even with this change though, note that
../src/configure --enable-mac64 --enable-sdk=/Developer/SDKs/MacOSX10.4u.sdk
also doesn't work because the CC=gcc-4.0 SUB_CONFIGURE_EXTRAS never gets set
for libffi. Hm, also just noticed that enable_futures_by_default=yes also
appears like it won't be set properly since it is with a uname -m == i386 check
as well. I suspect these i386 checks are to distinguish from ppc, so maybe they
should just change to uname -m != ppc in the darwin/mac sections.
