[lime-dev] Add PKGARCH:=all to all possible packages

Hi, dealing lately a bit with CI and build packages for all popular targets I found that most LiMe packages only use scripts like Lua and Bash and therefore don't really need to be compiled target specific. Idea is to add the PKGARCH:=all parameter which allows to install resulting packages on all targets without opkg protesting. I created an Pull request for that[1], please try! You can simply add `.diff` to the url and receive a diff which is usable with `git apply 370.diff`. Eventually we could offer generic feeds in the `/etc/opkg/limefeeds.conf` file and save a lot of build time. A few packages actually require compiling and are thereby not arch independent, namely: * dhcpdiscover * reghack * lime-webui Are the first two packages actively used? I've never stumbled across them. Best, Paul [1]: https://github.com/libremesh/lime-packages/pull/370
