Thanks for this patch. Support for MIPS IV was initially in Buildroot,
and got removed in 2014, as part of:
commit dd45fe0efb678a8a674330ad46b7641a3284dff9

arch/mips: remove deprecated mips1/2/3/4 support
Remove the support for generating mips1/2/3/4 code since it has been
deprecated for more than a year now.
Also remove the unnecessary kludges in packages for it.

This list is quite odd, because it's not even an exhaustive list of the
MIPS cores that we support.
Is mips4 supported by glibc, uclibc-ng and musl?
Since IMG kind of gave up on MIPS, we have difficulties in getting some
help in Buildroot to maintain MIPS support and address issues, so I'm a
bit cautious about adding more MIPS stuff.
