scons: In Check(Cxx|Link)Flag, only install the flag if it exists.
These functions where correctly returning whether a flag had existed,
and also correctly not installing it if asked not to. Unfortunately if
they *were* asked to install the flag, they ignored whether or not it
had actually existed to begin with.
