Yeah, possibly, if it's not too invasive.  I've not yet done any
research about what would need to change.

No idea.  But after a bit of man-page-reading I think it's probably not
the -O level that counts, so much as the fact that anchovy is using
-flto (link-time optimization) in CFLAGS.  I don't see any indication
that that's being selected by the buildfarm script itself, so it must be
coming from an environment setting of CFLAGS.
