Although the text of that warning is correct, users might find the
reference to eglibc slightly confusing if it's perf that they're trying
to build.
Also, as I mentioned in a different thread not all that long ago when
someone submitted a similar patch for gcc-runtime, the proliferation of
parse-time python functions to bash SELECTED_OPTIMIZATION around doesn't
seem like all that good a thing: this will cause extra overhead for
everyone, even those who are not using -O0 and have no interest in perf.
And, finally, it remains slightly unclear to me that this is really a
problem that the metadata needs to be solving. I haven't seen any
particularly convincing explanation of why this can't or shouldn't just
be fixed in the distro configuration.
