C++ feature checks: Filter out warnings caused by local configuration
In some environments the linker produces warnings like
warning: directory not found for option
warning: object file compiled with -mlong-branch ...
These do not affect the availability of C++ features we're checking,
so filter them out.
Fixes: #17850, #17947
