Pull up following revision(s) (requested by rin in ticket #1636):

        sys/lib/libsa/subr_prf.c: revision 1.30

libsa/printf: Do not fetch long va_arg as long long.

This does real harm iff all of the following conditions are satisfied:
(1) On ILP32 architectures.
(2) Both LIBSA_PRINTF_LONGLONG_SUPPORT and LIBSA_PRINTF_WIDTH_SUPPORT
    compile-time options are enabled.
(3) Width field is used with 'l' modifier.

This is an implicit-fallthrough bug, but unfortunately, GCC 10.4 cannot
find this out somehow...
