Use make -V VARIABLE | xargs ... to pass argument lists to program
so that this is safe even if VARIABLE is longer than kern.argmax.
There is another instance of CFILES which might need the same treatment,
and might be noticed when doing a "make links".
The same has to be done in RELENG_4 (on some different file).
