Many source files include e.g. wayland-protocols.h which should be found in the
sysroot but SDL wants to build its own headers from the XML definitions.

However the rules to generate those headers are only dependencies of the
top-level libSDL2.la object so can be built in parallel with the rest of the
objects, which can lead to interesting errors if the header is parsed by the
compiler whilst it's being written by another process:

| gen/wayland-client-protocol.h:3: error: unterminated #ifndef
|  #ifndef WAYLAND_CLIENT_PROTOCOL_H

Solve this by adding more dependencies so the generated files are built before
the primary objects.
