Yes. I wondered about that. I must admit I haven't tested it, but
since I don't think anything in the patch series is
endianness-dependent, I thought I should include armeb.
Do you prefer I remove it?

I think it is part of binutils-2.31, but we can probably still change
it, since the whole toolchain isn't available yet, no product should
rely on the target name.
It will be just painful to adjust the testsuite again
