[Buildroot] [PATCH] graph-depends: fix when $(O) is a relative path

[Arnout Vandecappelle (Essensium/Mind)]

The graph-depends commands cd into the CONFIG_DIR and run the script
from there. However, this means that when $(O) is a relative path, it
will no longer be correct.  Therefore, use $(BASE_DIR) instead of $(O).
