[U-Boot] [PATCH 02/11] buildman: Automatically create a config file if needed

[Simon Glass]

If there is no ~/.buildman file, buildman currently complains and exists. To
make things a little more friendly, create an empty one automatically. This
will not allow things to be built, but --fetch-arch can be used to handle
that.
