[U-Boot] help on using buildman

[York Sun]

Simon,

Can you shed some light on my trouble? I am trying to use buildman for
regression tests. I got inconsistency and am trying to find out why. Take one
example MPC832XEMDS_HOST_66 in this case (I randomly pick a failed board)

On one computer

$ ./tools/buildman/buildman -b working_upstream_qoriq --force-build
--force-reconfig MPC832XEMDS_HOST_66 -ve
No section: 'make-flags'
winegcc: gcc-4.5 failed
boards.cfg is up to date. Nothing to do.

No error.

You can see one error comes on and off. How can I debug it? I don't use python
enough to diagnose the code. Is there a way to dump the make command to check?
