This blocks us creating B2G desktop builds on linux for use by dev/qa/localizers and community.

We seem to be getting past this now and failing in 'make buildsymbols' (which is a RelEng issue, probably bug 759975). Someone pointed at http://hg.mozilla.org/mozilla-central/rev/c22083ebc853 as the thing that fixed it.
