That's a result of patching the kernel and thus moving away from the
v2.6.35.3 tag.

Dunno how you got this, was it really a clean 2.6.35.3?

CONFIG_LOCALVERSION does not play any role here, the documented way to
disable the plus sign is the LOCALVERSION environment or make variable:

make LOCALVERSION= all
