  [build] parallel build for firmwares

on OSX using sysctl seems to be faster than using system_profile and also more 
robust
(output is not named differently)

  Log Message:
  -----------
  [build] only build firmware in parallel with J=AUTO

by passing J=AUTO from toplevel make it will auto-detect the number of CPUs
Number of processes can also be explicitly set with e.g. J=4
Calling make without a J variable is the same as J=1 (serial compilation)

[build] parallel build for firmwares

- by passing J=AUTO from toplevel make it will auto-detect the number of CPUs
- umber of processes can also be explicitly set with e.g. J=4
- calling make without a J variable is the same as J=1 (serial compilation)

e.g. ```make AIRCRAFT=Quad_LisaM_2 ap.compile J=AUTO```
