I guess so although I don't see anything obvious when I
looked at the machine/configure.ac in both versions.

 I confirmed jmr3904 could build all tests with this gcc/newlib:

$ ~/rtems-work/tools/6/bin/mips-rtems6-gcc --version
mips-rtems6-gcc (GCC) 10.3.1 20211214 (RTEMS 6, RSB
bb9e049b103f3a47019a6cfad18e2b59c9e9ea97, Newlib eb03ac1)

That should have been the immediately previous version.
