I've backported 2 patches from master to warrior on Dec 27:
http://lists.openembedded.org/pipermail/openembedded-devel/2019-December/203803.html

In there "commit d5a8ec9e269d1f04a6cf78867ebf74a297f33258" added 
"-Wno-error=stringop-overflow" to BUILD and TARGET CFLAGS.

As you correctly mentioned GCC 4.8.5 doesn't support that flag.
AFAIK GCC 7 introduced it.

I will first revert that patch on warrior and send a fixed one (which 
respects the compiler version) later on.

Thank you for that catch and your email to the ml!
