Revorked basic variables initialization in configure

When you compile SDL2, generated sdl2.pc file contains leading spaces in
"Libs" variable, which threated by new CMake as error:

CMake Error at CMakeLists.txt (add_executable):
  Target "TestSimpleMain" links to item "-L/usr/lib64 -lSDL2 " which has
  leading or trailing whitespace.  This is now an error according to policy
  CMP0004.

This commit fixes that error by appending variable to list instead appending
to string.

Fixes bug https://bugzilla.libsdl.org/show_bug.cgi?id=4144

 dnl set this to use on systems that use lib64 instead of lib
