Default makepkg portability (was:10530: checksum verification does not work on BSD)

*PLEASE* edit the subject when you drift to another topic. Yes,
portability is NOT the original topic of this thread; checksum
verification on BSD systems is the original topic which is quite a bit
narrower in scope.

The whole point is avoiding situations when we do need OS-specific
checks and configurations. Take a look at the pacman and libalpm code-
you will notice no checks for definitions of things like LINUX, BSD,
DARWIN, CYGWIN (well one of these, but its documented and explained),
etc.

Portability means "runs everywhere", not "has a case in a switch
statement for each platform".
