Subject: [PATCH] Fixed bug 4357 - iosbuild.sh broken with SDL 2.0.9

Christoph Charles

The new source files for coremotion sensors don't seem to have been included correctly in configure.in. This leads to the build script ios-build.sh to fail at link time, complaining about missing symbols, namely about missing SDL_COREMOTION_SensorDriver.
