Is the default case for a package itself to know what is the best
optimisation option, or is the default case for packages to pick
"generic optimisation" where a good pkgsrc default can win over the
An all singing dancing option might be:
- a per package flag, the semantics of which are "this package knows
how to make good optimisation choices which will not lock it to a
specific CPU sub family"
- a pkgsrc option for "compiler optimisations" (defaults to added to
CFLAGS for packages which do not set the above)
- a pkgsrc flag for "no, I really know what I'm doing re
optimisations, override for all packages"
But as to whether its worth the work...
