Summary:                    [patch] Make. Parallel build on multi CPU host
Description: 
On multi CPU  host you can build project several times faster if you tell
'make' to execute several jobs at a time.

E.g. for dual core PC:
make -j 2

Asterisk Makefile doesn't support -j option too well because of overriding
$(MAKE) variable.

---------------------------------------------------------------------- 
I'm not a "makefile" expert by any means.  In fact, the "-j" option is new
to me.  This patch would seem useful if there existed a menuselect function
(or perhaps just an auto-detect in ./configure?) which automatically
detected the number of CPUs in the system and assigned the appropriate
value to the make options.   Many machines now come with at least two
cores, and often many more than that.  Having a default behavior that takes
advantage of the additional speed seems like it would be desirable.

Or is this automating too much?
