Some platforms (like those using Newlib) don't have ffs/ffsl. This commit adds a check to configure.ac for __builtin_ffsl if ffsl isn't found. __builtin_ffsl performs the same function as ffsl, and has the added benefit of being available on any platform utilizing Gcc-compatible compiler. This change does not address the used of ffs in the MALLOCX_ARENA() macro.
