Bash side of it's pretty easy to implement however needed, the problem 
here (and why imo USE_EXPAND came into existance) is getting those 
conditional nodes into the dep syntax evaluation without trampling 
other use vars.

And *-*-*-fbsd as a conditional node sucks in depends, is ugly, oh so 
ugly.  :)
