Minor fixes to link agianst SpiderMonkey trunk

This patch allows couchjs to link against the SpiderMonkey as it existed
in the mercurial hash 59c1e6bdb11 from [1]. This does *not* ensure
compatibility with CouchDB as there are other things that will also need
to be fixed. Specifically, the anonymous function issue for builtin JS
functions.
