Subject: build-perf-bisect: introduce -n option
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=781b9b1fe566c373d2bfc54501ac350e8be8045e;p=thirdparty%2Fopenembedded%2Fopenembedded-core-contrib.git

build-perf-bisect: introduce -n option

Causes no threshold to be required, making all results pass. Useful for
just measuring perf.
