[patch] remove build dependencies in bsd.ports.mk

[Nicolas Blais]

This may or may not be useful for the FreeBSD community but....

As I 'ls /var/db/pkg', I noticed a lot of ports I didn't use and that didn't 
have a +REQUIRED_BY file. Ports such as ezm3 and gcc-ooo that I could do 
without. So, what I did is a simple hack in /usr/ports/Mk/bsd.port.mk so that 
I can run 'make deinstall-builddepends' after a port is installed, and it 
will ask me to remove any build dependencies.

So far it works great, but I couldn't use the 'force (-f)' parameter in the 
deinstall target so I made a new target called interactivedeinstall. (I found 
out the hard way when I 'deinstall-builddepends' in cvsup and it removed my 
xorg-libraries...).

One could improve my patch by detecting if the port is already +REQUIRED_BY 
another port so it would not ask to delete it.
