No, this is bfd's.

Apparently, I made a mistake with original configure or there's some
internal inconsistency in platform naming.  I happen to have the old
build tree around and it lists --host=shl-unknown-netbsdelf1.6ZC
(apparently guessed by configure) which bfd knows about, but matches
as sh*-*-netbsdelf* and defaults to big-endian.

The kosher host to configure for seems to be "sh3le--netbsdelf" (sic:
"le").  The difference for bfd is only the DEFAULT_VECTOR, and it
choses the correct vector from debugged programs just fine anyway.

NB: bfd and opcode are in disagreement about platform naming.  bfd
will compile sh5 support only if explicitly asked for a sh5/sh64.
OTOH, opcode will compile sh5 support for 'unqualified' sh- and shl-
as well and will fail to link.  So the '3' in that sh3le is important
to prevent this lossage.  Oh, and note that it's "le", not "el".

So now that I found the name that gets correctly sifted through this
twisty maze of shell case statements, I really don't feel like
touching any of their pervert logic.

SY, Uwe
