Sets the WAFLOCK environment variable. This controls the name of the
lock file that waf uses to pass the build configuration from 'configure'
to 'build' and 'install'. Using a uniquely generated name based on the
parameters passed to 'configure' ensures that the source directory can
be configured for multiple different builds without conflicting (since
the lock file is stored in ${S})
