www/firefox from r310622

	
>Description:
	
www/firefox no longer uses more than one cpu when building even though it is marked and safe for multiple jobs.

In the build after all of the config a brief warning is shown:
  gmake: jobserver unavailable

  The rest of the warning says that gmake is forcing -j1 and one cpu 
  building

>How-To-Repeat:
	

>Fix:
To work around, set MOZ_MAKE_FLAGS in the build environment

MOZ_MAKE_FLAGS='-j6'
export MOZ_MAKE_FLAGS
make install
