Unfortunately whilst rerunning configure and make against a project will mostly
work there are situations where it does not correctly do the right thing.
In particular, eglibc and gcc will fail out with errors where settings
do not match a previously built configuration. It could be argued they are
broken but the situation is what it is. There is the possibility of more subtle
errors too.
This patch adds removal of the build directory (${B}) when configure is
rerunning, the sstate checksum for do_configure has changed and ${S} != ${B}.
We could simply use a stamp but saving out the previous configuration checksum
adds some data at no real overhead.
If we find there are things where we want to disable this behaviour with
CONFIGURESTAMPFILE = "" in the recipe, or users could disable it globally.

This is particularly helpful for eglibc and gcc which use split builds by
default and
are a particular source of reconfigure type problems.

Is it feasible to back port this to denzil? I've encountered what I
think are similar issues reconfiguring gcc for example.
One of the bugs above is open against denzil and the issue certainly
exists there. The patch should apply equally well there.
I'd suggest we let this settle in master for a week or two and then add
it to the backport queue if no problems arise.
Cc'ing Scott so he's aware of this.
I've added this to my denzil branch and will start doing build testing.

I'll be returning from travel tomorrow and hope to catch up with my
denzil backlog, and queue up a new build on the autobuilder.
