This removes the _ZNSt12system_errorC* pattern from the GLIBCXX_3.4.11
version, because it doesn't seem to be used at the moment, but inlining
changes being tested for PR ipa/58721 cause some new symbols to be
added to the library and exported with version GLIBCXX_3.4.11, which
obviously shouldn't be getting new symbols now.

This happened for Solaris previously, and Rainer disabled the pattern
for Solaris: http://gcc.gnu.org/ml/libstdc++/2012-10/msg00070.html
This patch does the same for all targets.

Tested x86_64-linux, committed to trunk.
