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

[Thomas Petazzoni]

commit: http://git.buildroot.net/buildroot/commit/?id=790df63d353b4987a5f2aee5c67ee73378757b06
branch: http://git.buildroot.net/buildroot/commit/?id=refs/heads/master

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).
