[PATCH] Update poky-feed-config-opkg to generate a useful package setup

[Gary Thomas <gary@mlbassoc.com>]

[-- Attachment #1: Type: text/plain, Size: 970 bytes --]

The current poky-feed-config-opkg package only generates a skeleton for the
opkg setups.  In particular, the base configuration file /etc/opkg/base-files.conf
is not filled in at all.

The attached patch fills this file in, using variables set by the
user (local.conf, site.conf, etc).  If left unset, the behaviour will
be the same as current.

One thing I found is that opkg is very noisy if there are databases
mentioned in base-files.conf that don't exist.  For example, on ARM
platforms, there are a large number of possibilities (arm, armv5, armv6, ...)
that are never populated in .../tmp/deploy/ipk.  The changes to this
recipe will prune the file to only include those ipk databases which
have actual files present.
