buildman: Make -I the default
At present buildman defaults to running 'mrproper' on every thread before
it starts building commits for each board. This can add a delay of about 5
seconds to the start of the process, since the tools and other invariants
must be rebuilt.
In particular, a build without '-b', to build current source, runs much
slower without -I, since any existing build is removed, thus losing the
possibility of an incremental build.
Partly this behaviour was to avoid strange build-system problems caused by
running 'make defconfig' for one board and then one with a different
architecture. But these problems were fixed quite a while ago.
The -I option (which disabled mrproper) was introduced four years ago and
does not seem to cause any problems with builds.
So make -I the default and deprecate the option. To allow use of
'mrproper', add a new -m flag.
