Sounds perfectly reasonable.  config.site is also loaded to late
to override some startup tests.
There is, however, a bit of a chicken-and-egg problem there.
config.site is loaded from $prefix by default, but that can be given
on the command-line.  So to have optimal behaviour, we'd need to

 1) check the command-line for --prefix
 2) load config.site
 3) check the rest of the command line
