Well, the traditional MIPS targets are BEING used for SVR4....observe:

ld/configure.tgt:286:    mips*-*-sysv4*) targ_emul=elf32btsmip ;;
 gas/conlfigure:2499:    mips-*-sysv4*MP*) fmt=elf em=tmips ;;
   bfd/config.bd:646:    mips*-*-sysv4*) targ_defvec=bfd_elf32_tradbigmips_vec

I think that using 'elf[32|64]_[big|little]mips' for Linux and SVR4 would
be a bad idea and would confuse things. Note that in 'bfd/elf32-mips.c' the
IRIX_COMPAT macro is hinged around checking for a traditional MIPS target
and will proceed to build IRIX flavored binaries if we are not using a
traditional target. The names for IRIX targets ARE currently
'elf[32|64]_[big|little]mips'. Changing binutils so that these targets will
now be for Linux/SVR4 and create ANOTHER target 'elf[32|64]_irixbigmips'
will add more bloat to binutils and be confusing to people. SVR4 already
uses traditional MIPS targets and Linux should as well. My vote is still
to make Linux use the traditional MIPS targets. It will be difficult to
convince me otherwise right now :).
