configure: Remove obsoleted -malign-{jumps, loops, functions}

Browse Source 
The GCC warns "cc1: warning: ‘-malign-loops’ is obsolete, use ‘-falign-loops’".
The Clang silently ignores -malign-{jumps,loops,functions}.

The preferred -falign-* forms have been supported since GCC 3.2. So, just
remove -malign-{jumps,loops,functions}.
