With all the knowledge from bug 1036894, and a few temporary hacks, it is possible to get a full compilation/linkage build in the compile tier.

This has the nice side effect of having some things build while libxul links. This however has the caveat of making js standalone clobber builds slightly slower because building js/src now waits for icu, but with bug 1036894 (and this one, actually), it's possible to work around this in many different ways, but I'd rather not wait on figuring what to choose. There are also further improvements I'd like to make that would allow building even more things while libxul links that would make js/src wait less for intl/icu. https://tbpl.mozilla.org/?tree=Try&rev=aa249f1b56a1

I *will* get this right. (android reds were a problem with bug 1043351 in the queue, and windows red is a race condition because of the removal of the config/export dependency that I'm now readding) https://tbpl.mozilla.org/?tree=Try&rev=640cbf58ff6c

Aaand with the toplevel Makefile.in change corresponding to last rules.mk change.
