Possibly, libsupc++/unwind-cxx.h needs to be included by stdexcept.cc.
However, it does seem that the compiler shouldn't be generating a
reference to a library function without an .import statement.  I did
look at the assembler output for stdexcept.cc and the only references
to __gxx_personality_sj0 were in the code itself.  For example,

        addil LR'__gxx_personality_sj0-$global$,%r27
	ldo RR'__gxx_personality_sj0-$global$(%r1),%r1

There is no .import statementy.
