Subject: buildman: Make sure that -o is given with -w
X-Git-Tag: v2020.10~256^2~17
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=88daaef19f985b6ba2f9c0f62eed5378d6d40ebd;p=platform%2Fkernel%2Fu-boot.git

buildman: Make sure that -o is given with -w

It is a bad idea to use the default output directory ('..') with -w since
it does a build in that directory and writes various files these.

Require that -o is given to avoid this problem.
