The options aot-compile passes to the compiler by default are
"-fPIC -findirect-dispatch -fjni". If you want optimization
you need to invoke aot-compile with -c "-O2" or something.
(FWIW aot-compile-rpm passes the contents of $RPM_OPT_FLAGS
which contains -O2 as well as all kinds of arch-specific
optimizations.)
