It would be nice to get to the bottom of this, still. It's not my
intent to require new binutils for linking against musl. Any idea why
it might have been failing? Are there verbosity level options to ld
that might help track this down?

By the way, how old were those binutils? I saw "firmware Linux"
mentioned, which was the predecessor of Aboriginal, so unless that's
just still landley's dir name, maybe these are a lot older than I
thought..
