mach and the build system store shared state in a common directory on the
filesystem. The following directory will be created:
{userdir}
If you would like to use a different directory, hit CTRL+c and set the
MOZBUILD_STATE_PATH environment variable to the directory you would like to
use and re-run mach. For this change to take effect forever, you'll likely
want to export this environment variable from your shell's init scripts.
