[Buildroot] [PATCH] Add support for custom post-build script

[nfrench at xtale.biz]

I am currently building my app using the tools in staging_dir to
build my app then I mount the built ext2 from binaries cp my program on
and build a new ext2

Is there a standard why to do this .ie
this custom post-build

would it be possible to document how to
add a simple Hello World app.  So that it gets built  with
buildroot or have I missed somthing in the docs.

Thanks

Nick
