api, cmd/api: exit status 1 during API check for Go1.5 beta 2

[ajstarks]

Running all.bash on Mac OS X 10.10.4 reports exit status 1 after the API check phase. (FWIW a working toolchain is built, and beta 1 had the same behavior)

I have this problem with Linux x86_64 using a 1.4.2 from source as a boot strap. This is also the same problem I had with 1.5beta1 and is documented here:

#11636

At the time, it was building (and testing) successfully from tip and it was expected that the next beta package would have the issue fixed.
