Add --with-static-standard-libraries to the top level
gdb should normally not be linked with -static-libstdc++. Currently
this has not caused problems, but it's incompatible with catching an
exception thrown from a shared library -- and a subsequent patch
changes gdb to do just this.
This patch adds a new --with-static-standard-libraries flag to the
top-level configure. It defaults to "auto", which means enabled if
gcc is being built, and disabled otherwise.

* configure: Rebuild.
* configure.ac: Add --with-static-standard-libraries.
