Proposed patch

The patch changes the behaviour so that md_elf_section_letter returns
(bfd_vma)-1 for error, anything else is assumed to be a flag and is merged,
this includes 0, this allows targets to ignore flags if they want (I think this
is pretty useful).

I've changed all the targets to comply, and while I was in the area I've
tweaked the error message so it includes the offending flag character, and fix
the capitalisation on the error message to match.
