[Buildroot] [PATCH 3/4] package: add <pkg>-rebuild and <pkg>-reconfigure

[Thomas Petazzoni]

We are often asked "how can I restart the build of a package ?" or
"how can I restart the build of package from the configure part
?". Obviously, tweaking with stamp files is possible, but not very
user friendly.

Therefore this patch adds two new per-package targets: <pkg>-rebuild
and <pkg>-reconfigure. They will respectively restart the
build/install or the configure/build/install of the package <pkg>.
