Use $(MAKE) when recursing

Browse Source 
Using 'make' directly means that the jobserver environment variables don't get
passed down, so sub-builds for example don't use -j.

This is documented as the wrong thing to do:
https://www.gnu.org/software/make/manual/html_node/MAKE-Variable.html#MAKE-Variable

Use $(MAKE) instead, and compile times drastically improve:

  acrn-devicemodel    do_compile   -13.5s   -89.6%      15.0s -> 1.6s
