I can finally give a good concrete case where I might need to do this (or
need some other very clever solution).
I have created a distcheck command for BRL-CAD that has a lot of
responsibilities, including doing a complete configure and build of BRL-CAD
from a source archive expanded from a CPack
If you are building on Linux, try
MAKEFLAGS=j8 make distcheck
I have successfully used the MAKEFLAGS environment variable to propagate
parallel build invocations through scripts that invoke make with fixed
options.

Reading through make documentation, seems setting -jx to MAKEFLAGS is a
no-op.
*The `-j' option is a special case (see section Parallel
Executionhttp://theory.uwinnipeg.ca/localfiles/infofiles/make/make_47.html#SEC46).
If you set it to some numeric value, `-j 1' is always put into
Yes, but only when setting MAKEFLAGS from within a Makefile. It appears
the rules do not apply when MAKEFLAGS is set by the invoking shell.
(And actually, current GNU make handles parallel execution differently
on Linux, using a job server that all make subprocesses use to
coordinate
Thanks Mike, good to know! David actually solved my problem for me with the
generator based conditional and the $(MAKE) variable, but that's a nifty
workaround to have tucked away.

Is there any way to customize the Makefile output from CMake to
include user-defined lines (say, something like #include
Makefile.inc) at the end of each Make file?

With GNU Make, you might do the following:
CMAKE_MINIMUM_REQUIRED(VERSION 2.8
