Yes, this will go away.
It was a last minute hack to preserve race-enabled packages in usual dirs in the
other build system. I will just align that other build system with go tool (i.e.
move race-enabled packages to linux_amd64_race).

Good question... I think it may be just (raceenabled && m->racepc != nil) since
I set racepc only in few places.

Because tsan expects thread ids to start from 0. But I think it may be moved to
the tsan runtime side.
