Hmm... that doesn't sound right on upstream Kernels.
For example, the extra version on the media_build current Kernel is:
Makefile:EXTRAVERSION = -rc2
So, I guess we'll need a different regex, like:
-e ' elsif (/^EXTRAVERSION\s*=\s*(\d+)\n/){ $$extra=".$$1"; }' \
-e ' elsif (/^EXTRAVERSION\s*=\s*(\S+)\n/){ $$extra=$$1; }' \
