[U-Boot] [PATCH v5 07/13] buildman: Add verbose option to display errors as they happen

Fri Aug 8 13:10:24 CEST 2014
Normally buildman operates in two passes - one to do the build and another
to summarise the errors. Add a verbose option (-v) to display build problems
as they happen. With -e also given, this will display errors too.
When building the current source tree (rather than a list of commits in a
branch), both -v and -e are enabled automatically.

checks out its own copy of the source code, so you can change branches,
add commits, etc. without affecting the build in progress.
