lm_sensors2 Makefile

[mds@paradyne.com (Mark D. Studebaker)]

Khali's point about having i2c and lm_sensors be the same is well taken.

I don't really see why the "default" kernel would be different than the
"running"
kernel. But I think that /lib/modules/uname-r/build is more likely to be
correct
than /usr/src/linux and so is a better choice. 
That's why I liked the patch. But just my opinion.

Dave, we've been searching for someone to generate current RPM's and
improve
our RPM support for quite a while. Be glad to have you do it if you are
willing.
