mozjs60 fails to build on mips:

/<<PKGBUILDDIR>>/js/src/jit/mips-shared/AtomicOperations-mips-shared.h: In instantiation of 'static T js::jit::AtomicOperations::loadSafeWhenRacy(T*) [with T = long long int]':

     static_assert(sizeof(T) <= sizeof(void*), "atomics supported up to pointer size only");
                   ~~~~~~~~~~^~~~~~~~~~~~~~~~

We can't upgrade gjs to a version that uses mozjs60 until either this is
fixed somehow, or gjs and its dependencies (notably GNOME Shell) are
removed from mips.
