This error is from our code, not meson's - the simplest fix would be to just
map android to linux, similar to how dragonflybsd is mapped to netbsd.  Blind
attempt attached.

It looks like that might be all that's required, as it looks like meson knows
that android doesn't properly deal with soversion.
