[RFC PATCH] allow arbitrary Linux kernel versions

[Johannes Stezenbach <js at sig21 dot net>]

Allow the user to specify a specific Linux kernel version.
In contrast to KERNEL_LINUX_CUSTOM crosstool
will automatically download the tarball (provided the
version number entered by the user is valid).
Using this also stops crosstool from downloading
the latest-greatest kernel after every crosstool update.
