ld: Undefined symbols:
_JS_Init

_JS_NewObject
Thanks,

Looking at the errors slightly more closely (you too can see this):
jstypes.h:231:71: jsautocfg.h: No such file or directory
That means you have not run jscpucfg. Makefile.ref should do this for
you in its $(OBJDIR)/jsautocfg.h rule. Debug why it didn't.
