This is crashing at
https://searchfox.org/mozilla-central/rev/61fceb7c0729773f544a9656f474e36cd636e5ea/js/src/threading/Mutex.h#39
which is a function that lives in mozglue:

https://searchfox.org/mozilla-central/source/mozglue/misc/PlatformMutex.h#29

and your linker is telling you it can't find the symbol.  It looks like you
didn't link mozglue in anywhere?  (Not really sure how mozglue works with
standalone SpiderMonkey...)
