ahh, yes.

Looks like:

        tx39.mt == tx39l.mt
        embed64.mt == embedl64.mt
        mips.mt == embedl.mt (!!! except for comments; this one is puzzling!)

so probably more could be collapsed later.

Yeah, for some reason i don't like using "mips*64".  dunno why it bugs
me, though.


Patch as re-tested with mipsisa64-elf gdb and checked in (trunk &
branch) is below.


thanks,

	* configure.tgt: Document need for special "mipsisa64" handling.
	(mipsisa64*-*-linux64): Handle as target linux64.
	(mipsisa64*-*-*): Handle as target embed64.
