Detect errors when failing to copy release kernels

[Pierre Pronchery <khorben%defora.org@localhost>]

		Hi there,

In the patch below, I let build.sh detect and bail when it fails to copy 
release kernels. It happens regularly to me, when re-building 
"releasekernel=..." locally with build.sh - for some reason the kernels in 
$objdir/releasedir/$arch/binary/kernel are created read-only - and then I 
end up using old kernel builds.

Let me know if it is fine to commit it.
Should we push this further, and detect and bail upon more potential 
errors?
