Yeah, I know that version is old and has been removed because of not building with GCC 4. The latter issue has been fixed and this old version is quite fast and has some advantages when used with X-forwarded ssh, so I'd like to rekeyword it. BSDs, I added you just for the case, feel free to remove. MIPS, there is no keyword on app-editors/emacs from you, but as eroyf always complains MIPS are so slow, this version could fit your needs.
I'll add ~ppc64 once a user requests so.
Linux/HPPA is not supported in the sources without some heavy editing, it seems. Emacs 21 will just have to make do.

We'll do as ppc64, keyword it if some user asks for it.
Not now...
I've added support for a 32 bit build on amd64. Please keyword ~amd64. (And feel free to fix the source to be 64 bit clean. I've counted 1531 warnings "cast to pointer from integer of different size".)
I've package.masked emacs-18* in profiles/arch/amd64/no-multilib and profiles/features/64bit-native.
