* 'build' target implemented.

* Additional variables which can be defined
  on per-arch basis (in Makefile.inc) introduced
  and documented in README.

+arch_makeflags
+
+  This variable may contain the make flags settings for the
+  make-kpkg invocation in the 'build' target. Currently it is
+  only used by amd64, where it should be set to something like
+
+  arch_makeflags = 'CC=amd64-linux-gcc V=1"
+
+added_patches
+
+  Setting this variable to non-empty value will cause an option
+  --added_patches to be added to the make-kpkg call in 'build'
+  target, followed by the contents of this variable. Currently
+  hppa is using it and it looks like ia64 have used it before.
+
+arch_with_subarch
+
+  Setting this variable to non-empty value will cause an option
+  --subarch to be added to make-kpkg call in 'build' target,
+  followed by the flavour for which the kernel is built. NOTE
+  that the contents of this variable are completely ignored,
+  any non-empty value indicates that --subarch option should
+  be added. In general, if you wish to add subarch support for
+  your architecture, you should contact kernel-package maintainer
+  to ensure that the flavour name correctly maps onto a kernel
+  subarch name. Currently only mips and sparc are using this
+  facility, and both of them should be fine.
