[luci] Broadening of the range of platforms in "Luci nightly builds"

[Bluse]

Hi Luci team,

We are heavily working on top of your nightly builds "Openwrt with Luci" - 
thx for that effort you are doing here !
Could you guys imagine to increase the compiled images towards more 
supported platforms ???
In our case we do use in our mesh around 15 ASUS WL-500GP with Atheros 
miniPCI and some AVila Gateworks (Intel Xscale).

It would be really nice to have a nightly LUCI for brcm47xx & ixp4xx & x86 
based on the current OpenWRT.

What do think about ?

Bye Bluse
