Subject: qemu.inc: Change kernel provider assignment to a weaker one
X-Git-Tag: uninative-2.1~95
X-Git-Url: https://code.ossystems.io/gitweb?a=commitdiff_plain;h=07e06abeb6b7ae5047c4b70818cd8873302e4940;p=openembedded-core.git

qemu.inc: Change kernel provider assignment to a weaker one

Currently we have local.conf included before qemu.inc, and ${DISTRO}.conf
after qemu.inc. They both possibly specify their expected kernel providers.
To let other config files override it in real use, this commit changes
kernel provider assignment to ??= .
