The Clang does not support -falign-jumps and only recently gained support
for -falign-loops. The -falign-jumps=1 should be tested beside
-fliang-loops=1 to avoid passing unrecognized options to the Clang:
clang-14: error: optimization flag '-falign-jumps=1' is not supported [-Werror,-Wignored-optimization-argument]
The -falign-functions=1 is supported by GCC 5.1.0/Clang 3.8.0. So, just
add the option unconditionally.

The GCC warns "cc1: warning: ‘-malign-loops’ is obsolete, use ‘-falign-loops’".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