Subject: [PATCH] avoid link latomic failure on CentOS 8 host
|
|
When host (such as CentOS 8) did not install libatomic, there was a
|
link failure on native. In fact, only target requires to link atomic,
|
the native does not. So link atomic for target only
|
|
Upstream-Status: Inappropriate [oe specific]
