alpha, mips, mipsel and ppc64 listed explicitly in SET_ARCH_DIRS

[Gary Benson]

Hi all (and specifically doko),

I just noticed that alpha, mips, mipsel and ppc64 are listed
explicitly in the SET_ARCH_DIRS bit of acinclude.m4, but they
don't seem to have any special behaviour that stops them using
the default case.  I know ppc64's "uname -m" says "ppc64", and
I seem to remember alpha's says "alpha".  What do mips and
mipsel do?  Any platforms that can be handled by the default
case probably should be.

Cheers,
Gary
