That means that the Makefile and xbps-src generated files are not required
anymore, and the xbps-src script can be used as is.
Bump xbps requirement to 0.35 and enable XBPS_INSTALL_ARGS by default.
The new xbps-src configuration file is `etc/conf` where you can
add your local overrides from defaults set via `etc/defaults.conf`.
To use this xbps-src, run these steps:
$ make
$ sudo make setup (to make chroot helper setgid)
$ ./xbps-src ...
