  From: Simon Glass <sjg@chromium.org>

Add a new global_data flag GD_FLG_ULIB to indicate that U-Boot is being
used as a shared library. This allows suppressing console output that
is inappropriate for library usage while preserving normal boot messages
for standalone operation.

For now the flag must be enabled by the caller and it has no effect.
