[PATCH/RFA] Add sh5*-*-netbsd* and sh64*-*-netbsd* targets

[Jason R Thorpe <thorpej at wasabisystems dot com>]

The 4 targets added are:

	sh5-*-netbsd*		SH5, big-endian, 32-bit default
	sh5l-*-netbsd*		SH5, little-endian, 32-bit default

	sh64-*-netbsd*		SH5, big-endian, 64-bit default
	sh64l-*-netbsd*		SH5, little-endian, 64-bit default

Changes to config.sub are also needed, will be submitted to config-patches
separately.

I'm particularly interested in a sanity-check on the change to tc-sh64.h.
Without that change, I get a "redefined" warning for that macro (the
original definition comes from tc-sh.h).

Also, bfd/targets.c listed the existing sh64 vectors, but didn't actually
put them in the targets array.  I did the same thing with the new sh64_nbsd
vectors.  What's the right thing to do, here?

The new elf{32,64}-sh64{,l}-nbsd vectors are needed, because NetBSD
does not use a leading underscore for user-visible symbols (this matches
the elf32-sh-nbsd behavior).

OK to commit?
