This test shows the amount of memory used by the system. Note that this is dependent on the user-space that is loaded when this program runs. Optimally, this program would be run as the init program itself.
Sorry to only chime in at v5.

I think the following is preferable: CC := $(CROSS_COMPILE)$(CC) It allows optionally setting a custom CC, as well as optionally CROSS_COMPILE. The only thing it doesn't do is choose gcc explicitly, but you shouldn't really do that anyway - unless you absolutely require gcc. Let the user choose their compiler by choosing where cc points. cheers
