Bug 1091505 - Run subconfigures in parallel. r=gps On automation, this brings Windows configure time on a clobber from 5:30 to 3:10. Sadly, because make needs to run under intl/icu/host before configuring intl/icu/target, intl/icu/host needs to be configured independently. Fortunately, that's not configured for normal windows builds anyways. Also, having multiple subconfigures sharing the same cache file is dangerously racy. Fortunately, not a lot do. In fact, only js/src and $_subconfigure_subdir do, so force the latter (only used for ldap sdk on comm-central) not to configure in parallel.
