Yes, benchmarks look fine.  Without --dynamic there's no noticeable
performance impact.  With --dynamic, gforth-fast is slightly faster,
which might be due to the mips-specific primitive relocatability checks
having no 64-bit opcodes in the opcode blacklist.  Not that any checks
would be needed.  Everything new enough to have 64-bit opcodes at all,
should not have any of the delay slots and instruction order constraints
these checks enforce.  Will have a look at that again, maybe relaxing
some checks we can speed 32-bit gforth-fast somewhat up (AFAIK Debian
nowadays compiles with -march=mips2, so if we detected cpu >= mips2 we
may disable some checks).
