Note: I'm running 9front. I can build on amd64 but not 386. Last attempt
was 1.5 on 386, bootstrapped with 1.4.2:
dl; go version
go version go1.4.2 plan9/386
dl; GOROOT_BOOTSTRAP=/usr/local/go
dl; ./make.rc

I understand Fish and Aram were at least able to build 1.5 on (Bell Labs)
386. I made noise about my failure at the time but I don't think anything
has happened in response. I did try bootstrapping with 1.4.2 binaries
supplied by Fish (and also a set provided by Aram) but got the same
results.
Beyond simply building, there are also still outstanding bug reports
about basic functionality that affect all versions of Plan 9. I don't
think there has been much movement there, either.
