Subject: configure: document ignored switches

Autostuff tradiotionnally have some switches to set host, build and
target systems, static or shared libs, and a bunch of others...

In the crosstool-NG case, they do not matter, as crosstool-NG is
just a set of scripts (there are C files, but they are compiled
after installation, at runtime, so it does not count).
