The qemu executable supports this use pattern (-cpu ?),
but it's unusual for configure.

Other options (--audio-drv-list=LIST, --audio-card-list=LIST)
show the available values in the help message (configure --help).

What about a similar help text for --target-list? Like this:

   --target-list=LIST       set target list []
                            Available targets: i386-softmmu ...
                            i386-linux-user ...

Users would not have to call configure twice to get the list of
available targets (the first call is configure --help because
they don't know whether it is --target, --targets, --targetlist
or --target-list).
