It is in make.sys indeed, the very first two lines:

CC      = C compiler
CCFLAGS = C compiler flags

If your make.sys doesn't have them, you must be using an old version.
Try regenerating it with the new "configure" script. (You've downloaded
the latest CVS version, haven't you?)
Run it this way:

./configure CC=mpcc

and it should detect your parallel compiler out of the box.
