build: add -Wconditionally-supported to strict_warn [PR64867]

The PR (which isn't resolved by this commit) pointed out to me that GCC
should build with -Wconditionally-supported to support bootstrapping with a
C++11 compiler that makes different choices.

PR c++/64867

gcc/ChangeLog:

* configure.ac (strict_warn): Add -Wconditionally-supported.
* configure: Regenerate.
