cmd/go: go install -race std fails with clang trunk

[fsouza]

After building go with clang from trunk (with some warnings, see issue #7339), it's not
possible to build the standard library for race detection:

Comment 1:

race detector is broken on tip.

Status changed to Duplicate.

Merged into issue #7334.

Comment 2:

Ops, sorry. I thought it was something with clang and didn't search for the issue.
