Detection lets you decide which code path to use internally in hosts
and plugins, but you can't reliably tell which GMPI profile is in use
by just checking the CPU type. Hosts running on borderline case CPUs
("acceptable" FPU performance) might chose to use either float or
integer samples, based on criteria that plugins cannot possibly be
aware of.
We have to make sure hosts won't load plugins using incompatible GMPI
profiles. "Normal" hosts that for some reason want to run plugins
written for embedded systems can do so, but normally, one would just
refuse to load such plugins.
