Adding myconf+=( --enable-64-bit-bfd ) immediately after use multitarget && myconf+=( --enable-targets=all --enable-64-bit-bfd ) in /usr/portage/eclass/toolchain-binutils.eclass fixes the problem.
Commenting out the added myconf+=( --enable-64-bit-bfd ) and remerging binutils again, the problem returns.

So it seem that whether 64-bit-bfd is enabled without an explicit switch is somehow dependent on currently installed binutils -- could be a bug in binutils build system.
Bug #444830 suggests that always adding --enable-targets=i686-linux-gnu,x86_64-linux-gnu might be a solution.
we used to do this, but then changed it in Bug 438522. guess we can re-enable it for the bi-arches ... but i can see some people who don't care about bi-arch and would want to disable it. i'll wait for that day though. http://sources.gentoo.org/eclass/toolchain-binutils.eclass?r1=1.121&r2=1.122
Thanks, I tested on building an x86-64 kernel. Was not aware of bug 438522 -- I assumed that 64-bit support on x86 would be disabled in gcc in unison with binutils.
