There is no mmix-elf target: if it's buildable, that's a
mistake.  I'm not sure what kind of abomination results, if it's
a goldblum-fly or karloff-frankensteins. :)

The target mmix a.k.a. mmix-knuth-mmixware assembles to ELF, but
links to MMO by use of the generic linker machinery.  You *can*
link to ELF by means of the linker option "-m elf64mmix".
