Looking at the old configure logic, I think what we do for a static
link is that we do a test compile, and if it succeeds then we enable
SDL, and if it doesn't we silently don't enable SDL (and I haven't
tested but I assume that this config without the dependencies
available as static libraries is going to fail that compile test).
Presumably Meson is complaining rather than just treating "don't have
a working static SDL and user didn't pass --enable-sdl" as
"silently don't enable SDL" ?

Don't need to fix this now; I guess we can do it later.
