Update of libsdl brokes tons of ports

[catap (Kirill A. Korinsky)]

Seems that update of libsdl at ​https://github.com/macports/macports-ports/commit/ddff16416716aaf2a1c522f7f94301e9f4df6496 had broken a lot of ports.

For example on macOS 12:

sudo port install --unrequested smpeg

You can always run 'port rev-upgrade' again to fix errors.

The same issue happens with libsdl_sound, libsdl_image and looks like that each prebuilt port which depends on libsdl
