kernel build from source

Hi,

I brought the wiki page on how to build a new kernel on Owl up to date:

http://openwall.info/wiki/Owl/kernel-build

This describes how to build custom Owl kernel RPMs and how to build a
non-RPM'ed kernel based on Owl's.  (It is also possible to build and use
mainstream kernels on/with the Owl userland, but this does not require
Owl-specific instructions.)
