21     # Usage:
22     #
23     # ecpu_check array_of_cpu_flags
24     #
25     # array_of_cpu_flags - An array of cpu flags to check against USE flags
26     #
27     # Checks user USE related cpu flags against /proc/cpuinfo. If user enables a
28     # cpu flag that is not supported in their processor flags, it will warn the
29     # user if CROSSCOMPILE is not set to 1 ( because cross compile users are
30     # obviously using different cpu flags than their own cpu ). Examples:
31     #
32     # CPU_FLAGS=(mmx mmx2 sse sse2)
33     # ecpu_check CPU_FLAGS
