Summary:                    use $(MAKE) -C instead of cd <path> &&
/usr/bin/gmake
Description: 
Hi,

in case of add_custom_target or add_custom_command if one uses
${CMAKE_MAKE_PROGRAM} like this:

[...]
COMMAND ${CMAKE_MAKE_PROGRAM}
[...]

Unix make generator will translate it as:
cd <path> && /usr/bin/gmake

which kills jobserver, I know that cmake code is agnostic of what is generated,
but it would be nice if actually $(MAKE) -C <path> was generated.

Steps to Reproduce: 
[palmowsk at suzuki bug]$ cat CMakeLists.txt
cmake_minimum_required(VERSION 2.6)

project(feature_request)

add_custom_target(run_make
    COMMAND ${CMAKE_MAKE_PROGRAM} -f ${PROJECT_SOURCE_DIR}/test.mk
)
[palmowsk at suzuki bug]$ cat test.mk
.PHONY: all

all: a b c

.DEFAULT:
        echo $@
        sleep 5
[palmowsk at suzuki bug]$ mkdir build
[palmowsk at suzuki bug]$ cd build/
[palmowsk at suzuki build]$ cmake ..
