Revert "don't compile tilecreator if MOBILE is specified"

The tilecreator crashes on Scratchbox when the cmake option TILES_AT_COMPILETIME is enabled (which is the default).
Disabling that option for Scratchbox avoids the crash as well. And it is the better solution.

This reverts commit 75736d69642e112b9ef86e891fb22bcbf83a4d4d.
