[ale] Use cloud guest to compile kernel

[Jim Lynch]

I've had situations where make failed with -j due to I guess race 
conditions.  I use -j which does 99% of the work and run it once again 
without the -j to pickup the stuff that didn't quite finish if the run 
with -j shows errors.  That works most of the time.

Jim.
