This is a known issue, specific to 9front on 386. Somewhere in November 2014,
just before the Go 1.4 release, there was a regression that caused this issue.
Sadly, I didn't have time to investigate it yet.
Plan 9 on 386 and 9front on amd64 are not affected by this issue
and are all able to compile and run Go 1.4, 1.5 and 1.6 successfully.
