[Buildroot] [git commit] infra: Add POST_RSYNC_HOOKS support

[Peter Korsgaard]

commit: http://git.buildroot.net/buildroot/commit/?id=e8ab39a7b5205e6a1a076fdda257a5baa32be765
branch: http://git.buildroot.net/buildroot/commit/?id=refs/heads/master

One of the use cases is for the 'local packages' to restore
the SCM info.  Some packages use this information to generate
version info during build time.  In this case, the local package
can have this hook to restore it by symbolic link for example.
