[PATCH v3 1/2] configure: Remove obsoleted -malign-{jumps, loops, functions}

[Fangrui Song]

GCC warns `cc1: warning: ‘-malign-loops’ is obsolete, use ‘-falign-loops’`.
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}.
