#
# SYNOPSIS
#
# AX_COUNT_CPUS([ACTION-IF-DETECTED],[ACTION-IF-NOT-DETECTED])
#
# DESCRIPTION
#
# Attempt to count the number of logical processor cores (including
# virtual and HT cores) currently available to use on the machine and
# place detected value in CPU_COUNT variable.
#
# On successful detection, ACTION-IF-DETECTED is executed if present. If
# the detection fails, then ACTION-IF-NOT-DETECTED is triggered. The
# default ACTION-IF-NOT-DETECTED is to set CPU_COUNT to 1.
