[Distutils] Build systems & working directories

[Nick Coghlan]

I'm currently trying out flit for a new project, and find it nicely
simple to use. However, I've also found a current constraint in terms
of the source tree layout: if you use a repo structure with a top
level "src" directory, then the flit.ini file needs to be in that
directory.

This means that in PEP 516 terms, the build command will need to be
"flit -f src/flit.init" rather than just a plain "flit".

I think the PEP could stand to be a bit more explicit that when the
specified build_command is invoked, the current working directory will
be the root of the source tree. (The PEP sort of implies this already,
but I didn't see it explicitly stated anywhere)

Regards,
Nick.
