Fails to build in js/src/shell with undefined symbols. I'm going to check in a temporary patch that copies the a couple of lines from js/src/Makefile.in (http://hg.mozilla.org/mozilla-central/annotate/b93de60dcb8e/js/src/Makefile.in#l402) to js/src/shell/Makefile.in to fix the bustage, but Ted mentioned that that should really be moved into configure.

Shark builds were removed in http://hg.mozilla.org/mozilla-central/rev/926651591417 (bug 1150312).
