Dear Fāng-ruì,

GCC warns `cc1: warning: ‘-malign-loops’ is obsolete, use ‘-falign-loops’`.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}.
In `INSTALL` under *The Requirements* at least GCC 5.1 is required.
* GCC 5.1.0 or later
Experimental support for clang 3.8.0 or later (results in much bigger
binaries)
for i386, x86_64, arm (including thumb), arm64, mips(el), powerpc, sparc64
So, this works.
