Fix testsuite failures caused by -static-libgcc and -static-libstdc++ options

[Cary Coutant]

This patch adds -shared-libgcc and -Bdynamic -lstdc++ options to
counteract the effect of the -static... options now passed in from the
top-level config. With a static libstdc++, the link of debug_msg_so
succeeds instead of printing several undefined variables, because we
suppress the printing of undefined variables when building a shared
object with unresolved DT_NEEDED entries.

Tested on x86_64. OK to commit?
