that explains the need for --enable-sjlj-exceptions
although it fails for me with:
Throwing out_of_range()
terminate called after throwing an instance of 'std::out_of_range'
terminate called recursively
Aborted

the config that worked for me was using unwind-dw2-fde-glibc.o
and without --enable-sjlj-exceptions

this file is always there, independently of the fact that you use 
sjlj-exceptions or not (for the no-case it is empty)

Well, I did the tests with a somewhat modified uClibc-svn, but I think the 
dependency lies in the gcc patches (that were also modified here, the 
tests were done in a gentoo environment).

I will redo the test
unwind-dw2-fde.o + --enable-sjlj-exceptions on a PPC box
