buildman: Allow make flags to be specified for each board
There are a few make options such as BUILD_TAG which can be provided when
building U-Boot. Provide a way for buildman to pass these flags to make
also.
The flags should be in a [make-flags] section and arranged by target name
(the 'target' column in boards.cfg. See the README for more details.
