[PATCH] reboot-mode: put the build artifacts in ${B}

[PATCH] reboot-mode: put the build artifacts in ${B}

[Bartosz Golaszewski]

From: Bartosz Golaszewski <bartosz.golaszewski@linaro.org>

We should output the compiled executables into ${B} and install them
from it as well. Currently we put the build objects in the source
directory. While at it: don't assume we're already in the source
directory and instead prepend the source file with ${S}.

By default B=${S}, so this hasn’t changed anything.

I'd say it's still more semantically correct, no?

Personally, I prefer to use S/B only in the case where they’re actually different directories and the latter has been wiped clean on every build.
