If you pass --enable-skip-subdirectories then configure will skip
configuring or reconfiguring libraries and simply configure the FS
core itself.

The default remains the same: we show the huge ClueCon nag banner on
startup and in fs_cli.

However, if you pass --disable-huge-cluecon-nag, no banner will be
shown.

If you pass --enable-modest-cluecon-nag, a modest text-based ClueCon
reminder will be shown instead.

FS-4305: --resolve When libvlc is unable to decode the audio fast enough for the local stream player, use multiple very quick 1 sample chunks of silence to fill in while libvlc catches up.

This was causing the build to fail if mod_sonar was configured to
build.
