It was originally added in
https://cgit.freebsd.org/ports/commit/lang/luajit/Makefile?id=d2ac3fee9c894bb6f10ab489a4b165f974fc1b03.
The review (at https://reviews.freebsd.org/D13804) says:
Successfully built on powerpc. Does not build for powerpc64, though.
Later, that was copied to luajit-devel.
Here's the most recent build on powerpc64le:
https://talos.anongoth.pl/data/latest-per-pkg/luajit-devel/2.1.0.20220815/powerpc64le-default.log
So that:
.if ${ARCH:Mpowerpc*} || ${ARCH:Mmips*} || ${ARCH:Msparc*}
can be replaced by just:
.if ${ARCH} == powerpc || ${ARCH} == powerpcspe

If you wish, the mips* and sparc64 parts can be added too, but I don't
think there are any users left.
