[Buildroot] [PATCH 1/1] force rsync of local package and try to rebuild it with its dependencies

[Anthony Viallard <viallard@syscom-instruments.com>]

The purpose of this patch is to force rsync of local site packages and
rebuild them if their source code has changed. Therefore, if the source
of a package has changed, it will be rebuild if you type make or
make <pkg>. Likewise, if a package has a library dependency which is
local site package too and you type make <pkg>, the library will be
rebuild if the source has been modified.

This behavior is pretty useful if you use buildroot with many of your
own packages. Especially if you share these packages with a developer
team through a version control system like git.
