[RFC] bsd.port.mk: Record OPTIONS into /var/db/pkg on install

[Bryan Drewery]

Hi,

While developing on ports-mgmt/poudriere I've added support to
automatically rebuild packages if the selected options in /var/db/ports,
or make.conf change. This so far has worked well with pkgng as it
records the OPTIONS selected into the package already.

By suggestion of bapt, 'pretty-print-config' is used to compare the
packaged OPTIONS to the selected OPTIONS. This has worked great for pkgng.

Just today I added support [1] to poudriere for pkg_create(1) packages
by storing the 'pretty-print-config' into the
/var/db/pkg/PKGNAME/+CONTENTS as a comment:

@comment OPTIONS:`make pretty-print-config`

I'd like to add it to 'fake-pkg' so that the @comment is saved on every
port/package creation.

This may potentially benefit portmaster and portupgrade as well.
