targets.mk

Add x86 config (for PC)
Add target for alix

Add new profile for medium-node (small+tinyproxy+ath5k)
Remove ath5k from small-node profile
Create specific configs for tl-wdr4300/3600 since they use big-node profile

Adds a new way to generate/store the configuration files for each target:

And individual configurations (optional) which can be used to specify extra options for the device

Adds support for new special target "ar71xx" which compiles the firmware for all atheros AR7/9 devices.
