Subject: scripts/runqemu: Fix MACHINE regex
X-Git-Tag: lucaceresoli/bug-15201-perf-libtraceevent-missing~36126
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=22c0668d9e0a22c095d78bab7b45ef4f803dd0d1;p=thirdparty%2Fopenembedded%2Fopenembedded-core-contrib.git

scripts/runqemu: Fix MACHINE regex

When runqemu tries to determine the MACHINE variable from a
kernel or vmdk filename that doesn't contain any known machine
name, the variable gets set to the filename. It should remain
unset and cause an error.

[YOCTO #2890]
