Hmm, looks like the patchlet might be enough to do the trick. It looks like I
misread the logs. Apologies, the link time failure was actually with == in 

In function `std::type_info::operator!=(std::type_info const&) const':
/work/gcc/libstdc++-v3/testsuite/18_support/type_info/hash_code.cc:51:
undefined reference to `std::type_info::operator==(std::type_info const&)
const'


Looks like it fixes my issue on ARM.
