Didn't work on mmix-knuth-mmixware.  I assume by "Fix nm
--size-sort on non-elf targets" you actually mean "Fix nm
--size-sort on non-elf targets where symbols have a size
attribute", else please shout.  I committed the following.

Conceptually it's wrong to xfail the test for targets where it's
(by design) not supposed to work; it should instead be skipped.
Though, adding skip-machinery would just clutter up the code for
no actual benefit, at least when those targets that should be
skipped is an insignificant number of one, IMHO.  To the point,
nm --size-sort should actually be made to work for those ECOFF
targets, right?

	* binutils-all/nm.exp: Xfail test for nm --size-sort for
	mmix-knuth-mmixware.
