Only try to run the libjpeg-turbo test program if we aren't cross-compiling. In a cross-compile environment, we'll settle for just making sure it compiles and links. Even though that can theoretically produce situations in which the wrong libjpeg is linked, such situations would be exceedingly rare in a cross-compile environment, since there is no "system libjpeg" to accidentally link with.
