need ports example

[Richard Welty <rwelty@averillpark.net>]

i would like to be pointed towards an example of a port that
uses SUPPATCHFILES in support of a flavor. i am making
the assumption that i can use :0 in the usual way, e.g.

MASTER_SITES0=	http://duncanthrax.net/exiscan-acl/

SUPPATCHFILES=	exiscan-acl-4.30-14.patch:0

to specify a patch file to be fetched for the exiscan variant
of the exim port.

i just want to see a Makefile that does something like this
already.

thanks,
  richard
