Andrew J. Hesford 74e0a12915 build-style/python3-pep517: make sure ./build exists in do_install
This allows templates to override do_build and not have to create the
build subdirectory used as TMPDIR in do_install; failure to create this
directory will cause pip to use (and pollute) /tmp in the masterdir.
