I think the "build configuration" is the set of all "build configuration
options" and --enable-posix is one of these options.
I would avoid the name "configure". Maybe we have some time in the
future a "waf config --enable-posix".

This is a link-time configuration. I think "application configuration"
is used in some places for it, although the application is not
configured. What is configured is the RTEMS executive.
