Subject: [PATCH] spidermonkey: fix host, target settings
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

spidermonkey doesn’t use the autotools build, host, target convention.
Instead it considers ‘--host’ to be the autotools’ ‘--build’ and
‘--target’ to be the autotools’ ‘--host’! As a result, we cannot
safely use “configurePlatforms”. Instead, we must manually set these
flags.
