Build fails because of parallel make
Hi,
Pythonz helps me to do my work very much. Thank you for useful tool.
I encountered a problem that pythonz install 3.5.2 failed.
After several minutes of search, I noticed that it is because make -j 32 (The machine I use has 32 logical cpus. make -j 2 also fails).
I changed installer/pythoninstaller.py to force to build Python without -j option and build succeeded.
Though the fundamental reason may reside in my environment, I think it is helpful that install command has an option to build Python serially.
It is like pythonz install --serialcompile 3.5.2.
I did some work to make Pythonz to do it. I'll make a pull request if you don't mind.
Hi! It's a bit weird that it fails, but a PR making the parallel jobs configurable would be OK!
