That's what I use.

Probably you are talking about an incremental build. Lars refers to a
C.I. build, which always does a full build, starting with `git clone'
(or `git clean -fdx && git pull'), then `autogen.sh', `configure' and
`make bootstrap'. What takes 4.5 minutes in my machine starts with
`autogen.sh'. The C.I. system would also run the test suite.
