Fixed bug 4544 - SDL2.m4 SDL2.framework patch made it impossible to fail detection

Stian Skjelstad

check if $sdl_framework is set, before checking if directory exists

Patch that was merged here https://hg.libsdl.org/SDL/rev/9befd0acb9ef made it impossible for the SDL2 detection to fail, since one of the if statements fails to check if a variable is set or not.

if test -d $sdl_framework; then

can evaluate to true in some shells. I guess it falls into undefined behaviour when looking at the POSIX standard.
