I well understand all these problems but you missed !empty check
Everything set in tools.<platform>.mk is _not_ overriden by
tools.common.mk, i.e. in case you know exactly that xxx is broken on yyy,
set an alternative manually in tools.yyy.mk.
Instead of runtime checks (I agree this task is not so easy to implement)
you can make some additional checks in
this is not a offering, just additional possibility.

Not capabilities, just a more flexible way to detect the _presence_,
at least for now.

I know, I know. I just read about "NetBSD philosophy"
and now I'm hearing about pkgsrc philosophy "in practice" ;)

Do we really understand each other?
