Subject: cmd/dist: check more GOOS/GOARCH combinations in mkdeps.bash
X-Git-Tag: go1.6beta1~437
X-Git-Url: http://www.git.cypherpunks.su/?a=commitdiff_plain;h=1860a0fa571ff13ed2c4a23d50d55945720c86bb;p=gostls13.git

cmd/dist: check more GOOS/GOARCH combinations in mkdeps.bash

The current mkdeps.bash just checks for dependencies for GOOS=windows
with the current GOARCH.  This is not always accurate as some package
imports only happen on specific GOOS/GOARCH combinations.  Check a
selected, easily changed, combination of GOOS/GOARCH values.

This generates a deps.go identical to the one in the repository today.

Fixes #13221.
