Subject: buildman: Don't show a stacktrace on Ctrl-C
X-Git-Tag: v2016.11-rc2~10^2~37
X-Git-Url: https://git.sur5r.net/?a=commitdiff_plain;h=2f2566482fc5c24557126043394ce82088f60262;p=u-boot

buildman: Don't show a stacktrace on Ctrl-C

When Ctrl-C is pressed, just exited quietly. There is no sense in displaying
a stack trace since buildman will always be in the same place: waiting for
threads to complete building all the jobs on the queue.
