linux: add support for 3.x and -rc versions
The assumption that all kernels are in http://www.kernel.org/pub/linux/kernel/v2.6/ is no longer true: versions 3.x are in separate directories. We now compute the directory name from the major and minor versions of the version provided by the user. This assumes that the 3.1 version will be in a /v3.1/ directory, which we don't know yet because the 3.1 cycle hasn't started yet. At the same time, we add support for the official -rcX versions. Patch tested by compiling 3.0-rc6, which Buildroot has successfully downloaded and built.
