failed to finish build-cross.sh on mac pro (yosemite)

[hd51515]

the issue seems to be "but available 0G < threshold 11G" and "/usr/src/go/pkg/tool/linux_amd64/6l: running gcc failed: Cannot allocate memory". this is with the code i checked out just last night

sudo ./build/run.sh hack/build-cross.sh
