Fixing this would be trivial:

--- config.gcc  (revision 114538)
+++ config.gcc  (working copy)
@@ -1560,7 +1560,7 @@
        tm_defines="MIPS_ISA_DEFAULT=3 MIPS_ABI_DEFAULT=ABI_O64"
        use_fixproto=yes
        ;;
-mips*-*-rtems*)
+mips64-*-rtems | mips-*-rtems*)
        tm_file="elfos.h ${tm_file} mips/elf.h mips/rtems.h rtems.h"
        tmake_file="mips/t-elf t-rtems mips/t-rtems"
        ;;


Some fundamental questions, I can't answer, however would remain:
* Is such a mips64-*rtems* target useful at all?
* Has mips64-rtems* (before having added le/be multilib variants) ever
been useful.
* Can "mips64" be implemented as multilib variant of "mips"?
