linux: support a space-separated list of patches
The kernel being a component that often needs a fairly important set of changes to be adapted to a particular hardware platform, having maximum flexibility on the patching process is a nice thing. Therefore, as per the discussions from the Buildroot Developer Day, we add a mechanism to apply a list of patches (that could come either from URLs, local files or local directories).
