these are attached in the s390-ia64-mips-sparc.diff.gz:

        * config/abi/post/s390-linux-gnu/baseline_symbols.txt: Update.
        * config/abi/post/ia64-linux-gnu/baseline_symbols.txt: Likewise.
        * config/abi/post/mips-linux-gnu/baseline_symbols.txt: Likewise.
        * config/abi/post/sparc-linux-gnu/baseline_symbols.txt: Likewise.

ok for the branch and the trunk?
