I've just been looking at the open bug related to this
(http://bugzilla.yoctoproject.org/show_bug.cgi?id=1379) and I can't
reproduce an issue with layers ending with -numeric causing a
problem :/.

In the above example, 

recipies/linux/linux-wrs/defconfig

is the correct path since PN == "linux-wrs". (you had linux-wrs_git).
Could you check whether the layer numeric part is a red herring please
and whether the above path works?

Cheers,

Richard
