PR61536 is a case where linking fails on arm-linux-gnueabi* andarm-eabi* systems as the C++ ABI for ARM specifies out of linecomparison operators for typeinfo.

Rev r211355 tightened the symbols exported by libstdc++ a bit too muchwhich caused some carnage in the test results for arm-linux-gnueabihf.

Paolo proposed this on the bugzilla and asked if I could commit it. I'vetweaked the comment slightly.

Tested on arm-none-linux-gnueabihf and verified the link time failuresnow disappear.


Applied to trunk.
