mips gdb/sim build failure on Darwin

[Joel Sherrill]

Hi

This looks like we need to bump the hash, submit a patch, or change to
building with -Wno-error
(https://lists.rtems.org/pipermail/build/2021-November/030047.html).
Any ideas?

FYI Chris.. this one may be on you to see if a hash bump fixes it.
