commit a786a680476fd605f78b11ff60cd074d03f2b57f
Author: Raymond Danks 
Date:   Wed May 30 16:03:48 2012 -0600

Improve parsing of --cpu parameter in abuild script.

* -c "" need never be tested if getopt params are handled; fail abuild script when getopt parsing fails
    * use expr to resolve numeric test fails with -c max
    * cpus variable may be being passed in the environment.  Don't overwrite MAKEFLAGS if it is not.
