ports cross-compilers vs. native toolchain

I'm trying to build a customized u-boot (so that I can
add the bootelf command, which is needed to chain
Rafał's ubldr version of loader(8)). Of course, I'm trying
to build this from TI's sources customized for this board,
which means I'm not using the FreeBSD-customized
sources from denx.de.
Since ubldr is built with the native cross-tools, I've been
trying to build u-boot the same way, but I've run into
a few problems that make me wonder if it would make
more sense to build u-boot with the cross-* ports instead,
hence my question. (If I understand correctly, ubldr
calls into u-boot, so the two need to be built
compatibly, hence the question.)
Sounds like I should keep poking at u-boot with the
native cross tools….
Unfortunately, the native cross-version of ld is crashing,
and I have not yet been able to successfully build a debug
version of the native cross tools so I can figure out why.
I'll no doubt have more questions very soon. ;-)
