No, it should be effective anywhere - unless it's being overridden later on. In 
recent versions of bitbake, the -e option will show for each variable how the 
final value got set, you should be able to see where it is being overridden 
from there. Alternatively with older versions you should just be able to "git 
grep" for the value in each of the layers you have enabled in order to find 
where it is being set.

Are you sure you really need your own version of linux-libc-headers? Most of 
the time it is not necessary for the version to match that of the kernel you 
are using.

Cheers,
Paul
