Title: Remove usage of HAVE_SDL for external programs that use STLL

It doesn't make sense to force programs using STLL to define HAVE_SDL. Whoever includes layouterSDL.h does want to use SDL. There's no ambiguity here to solve.

This change ensures that HAVE_SDL remains only for the internal STLL implementation (layouterSDL.cpp).
