Subject: buildman: Add a test helper for creating a line prefix
X-Git-Url: http://git.dujemihanovic.xyz/?a=commitdiff_plain;h=c9dd80b3d462beeb6af18ca0b56265ff408fe7f8;p=u-boot.git

buildman: Add a test helper for creating a line prefix

The split/join code is repeated in a lot of places. Add a function to
handle this.
