Subject: Bug 1654112 - Suppress -Wclass-varargs warning in logging.h. r=ng

This needs some investigation to see why we get this warning when it is not
present upstream.

Since both were doing the same thing for different compiler chains,
also includes:
Bug 1654112 - linux build fix (pragmas) for base-toolchains* . r=ng
