Makefile.local

[Alex Dupre]

What's exactly the purpose of Makefile.local? I ask you this because 
today I received some messages complaining that ports ignore WITH_ and 
WITHOUT_ knobs placed in Makefile.local. It doesn't seem to be the 
correct way to set knobs, since that makefile is included only after 
bsd.port.pre.mk (and usually ports check for knobs before it), but many 
users seems to do it in that way. So, if this practice is incorrect we 
should clearly state it so users stop complaining, otherwise we have to 
fix a lot of ports.
