Don't show checks for command line options to make configure less verbose

The results of the checks for the command line options are not useful to show
as presumably the user already knows which options were used for invoking
configure, and so the results of these checks are known as well (with the only
exception of --with-xxx options when configure detects whether to use the
system or the built-in version of the library on its own, but we already
summarize the results of these checks at the end anyhow).

Just don't flood the user with all the messages about checking this and do our
job silently.
