I think it affects anyone using ld.bfd for big-endian ARM code. The
ideal behaviour is probably:

1. >=v7 (& v6m) code must pass --be8  (CPU only understands BE8 output)
2. <=v5 code mustn't pass --be8 (CPU does not understand BE8 output)
3. v6 code may or may not. (it's configurable in SCTLR) It probably
should for neatness, but unfortunately compatibility with GCC probably
requires us not to.

Cheers.
