I think #2 is a separate issue - but it's probably possible to be lazy
and not do #2 if we do #1. I'm not sure #3 can be made to work
safely, which is probably the reason Debian has fully gone with just
If doing #1 it should probably be validated across architectures
Pkgsrc supports (or turned on for specific architectures only) as
libjpeg-turbo is crammed full of chip-specific hand-crafted assembly.
