Forgot to mention that also tried on 2.0 to configure with
"--target=mipsel --with-platform=loongson" prior to the make steps,
and that didn't help.  I went back to the "guesses" by configure,
cause the alternative besides not helping further was generating
unusual (at least to me) /etc/grub.d files, :-).  The point is that it
didn't work either...
