[Buildroot] [PATCH 2/4] package: remove stamp files in <pkg>-dirclean

[Thomas Petazzoni]

When the package build directory was a real directory, then removing
the directory was enough to remove all its stamp files. However, now
that the build directory can in fact be a symbolic link to the real
source directory, we need to explicitly remove the stamp files before
removing the symbolic link. Otherwise, next time the symbolic is
re-created, some old stamp files would be found.

Unfortunately, there is still a bug: if one does a global "make
clean", the symbolic links are removed since $(BUILD_DIR) is removed,
but not the stamp files. Should we create the stamp files outside of
the package build directory ?
