           Summary: busybox built fails if we use an override src dir
                    BUSYBOX_OVERRIDE_SRCDIR and that dir does not contain
                    .config

when one tries to make busybox this fails because the
BUSYBOX_POST_EXTRACT_HOOKS are not run (we rsync from another directory).

The solution to that I've came up with is to either change the
BUSYBOX_POST_EXTRACT_HOOKS to BUSYBOX_PRE_CONFIGURE_HOOKS or add another hook
BUSYBOX_PRE_CONFIGURE_HOOKS += BUSYBOX_COPY_CONFIG

(the worst case scenario with the two hooks will be to copy the same file
twice)

the proposed solution is the following:

diff --git a/package/busybox/busybox.mk b/package/busybox/busybox.mk
index d18b6d0..17e8b7e 100644
--- a/package/busybox/busybox.mk
+++ b/package/busybox/busybox.mk

 # We do this here to avoid busting a modified .config in configure

A question to buildroot developers: what do we do with this patch? The
different components using .config files all handle it differently: 

busybox copies its .config from the post-extract hook.
linux copies its .config in the configure_cmds.
uclibc copies its .config from the post-patch hook.

The busybox behavior allows a user to change .config, then re-run the configure
step and keep the user's changes.
For linux this is not true: if you change your config and re-run the configure
step, your changes are lost. If you change your .config and expect to keep the
changes, you can only rebuild, not reconfigure.

This patch proposes to line-up busybox more with how the linux kernel handles
it.

This raises the question: what do we want, what should the behavior be?

Personally, I haven't had a big problem with the linux way, and thus would
accept the principle of this patch. But I don't have a very strong opinion on
this...
