Subject: devtool: modify: use B=S if that is the default for the recipe
X-Git-Tag: 2015-10~2057

devtool: modify: use B=S if that is the default for the recipe

Makes the build succeed for packages which do not support separate build
directory, e.g. zlib. The same outcome could be achieved with the
--same-dir option, but, it's generally hard to tell if a random package
would need that option. The negative side effect of this patch is that
dev srctree (of some packages that build fine without this modification)
gets dirtied by build artefacts.
