libstdc++: Suppress an attribute suggestion warning [PR116853].
This warning is triggering during the build and breaking bootstrap on
at least two targets. The warning appears valid, but the final fix for
it is not yet clear.
In the meantime, to restore bootstrap, the following patch ignores the
warning in the relevant code section.
PR libstdc++/116853
libstdc++-v3/ChangeLog:
* include/bits/basic_string.h: Ignore suggest-attribute=format
warning when using posix vsnprintf in to_string() implementations.
