I looked into the mips header files and saw a ghastly WRONG thing in there:
both little-endian and big-endian mips systems have "mips" for MACHINE_ARCH.

${MACHINE_ARCH} defines a set of binary formats that are uniform across that
${MACHINE_ARCH}.  For example, all m68k bins are the same format, so they
all have the same ${MACHINE_ARCH} - m68k.

Using "mips" for both big-endian and little-endian sets MUST be changed,
regardless of the effects.  Leaving it as-is will break a lot more than just
config.bfd - it breaks the entire concept of ${MACHINE_ARCH}-global binary
sets (not to mention the concept of binary pkgs).

Now, the question is how to do it:  make a new "mipsle," perhaps?

(Binary pkg/GNU people: it's rather trivial to set MACHINE_GNU_ARCH fr each
platform type as necessary.  Thank my mods for the arm32 guys.  :)
