Simon Glass 8e605a5e3e buildman: Automatically create a config file if needed
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.
