Subject: Update Portage to support multiple binhosts.
X-Git-Tag: v2.2.0_alpha20~93
X-Git-Url: http://git.tremily.us/?a=commitdiff_plain;h=7f84548b516d30de43118d58e6bc03c8739a0967;p=portage.git

Update Portage to support multiple binhosts.

BUG=chromium-os:11295
TEST=Build x86-mario with multiple binhosts (board binhost, preflight binhost)
     and verify that binaries are picked up from both binhosts. Also verify
     that if one of the binhosts fails, the other binhost is used correctly.
