That's my goal, but it's a bit of an involved change and will take
some time to make sure we don't introduce new corner cases. I'm sorry
that I didn't catch this before the first ifunc use went in -- lld has
been the default bootstrap linker (via buildworld or kernel-toolchain)
since mid-Jan and this problem slipped my mind. I added the error in
the meantime to avoid the silently broken kernel case that you
unfortunately encountered.

The low-friction method of getting past this in the interim is to just
use ld.lld as the system linker:
# ln -fs ld.lld /usr/bin/ld
I'm just waiting on an update to the lang/ghc port and another exp-run
before that becomes the default.
