This says "if the KBUILD_VERBOSE variable is not empty and is not equal
to 1, then the result of this evaluation is the character "@"; otherwise
it's the empty string".

The filter-out function removes the words matching the pattern given (in
this case the static string "_all") from the list of words in the second
argument.  MAKECMDGOALS is the list of goals provided on the make
command line (if any).  So this says "take _all out of the list of goals
provided on the command line, then put it at the end".
