Adding a new variable

Hello there!

After reading a blog post linked on Hacker News, I added a new
Makefile variable, #J, which stores the number of parallel jobs, that
is the command-line parameters -j and --jobs (corresponding to the
job_slots variable in the source code)

I don't know if this can help but if so, feel free to merge my make
repository from:

    https://github.com/esantoro/make

The license of the code is the same as GNU Make.

Example:
- -----------------------------------------------
address@hidden ~/sources/make/test $ ./../make
Jobs: 1
address@hidden ~/sources/make/test $ ./../make -j2
Jobs: 2
address@hidden ~/sources/make/test $ ./../make --jobs 32
Jobs: 32
address@hidden ~/sources/make/test $ cat Makefile
default:        Makefile
        @echo Jobs: ${#J}
- -----------------------------------------------

Have a nice day/night,
