Hmm, yes, you get BFD_ARCH_SIZE == 64 if either the host or target is
64 bit.  That would make building the 32 bit target from a 64 bit host
wrong.  I'll see about a different solution.

No, I'm not sure but did build a few 64 bit targets.  Reducing the
allowed inputs was intentional, and I suppose I should have said so
in the ChangeLog.  I figure that eg. [45][c4] was meant to match 4c
or 54, as they were the values I found.

Sure.  Wasn't that what I said?

OK.

Some of which will need to be removed if -Saix goes.

OK.  I intended to make the commit in a number of pieces, and this is
one of the obvious bits to do separately.

Lots of "relocation truncated to fit: R_PPC64_TOC16_DS toc", because the
generic srec linker doesn't do any fancy relocations.

I was lazy, I admit it.  Thanks for looking it over anyway.  I'll commit
a number of changes that provide extra infrastructure, and we'll go from
there.
