Since automake already sets per-library CCASFLAGS to $(AM_CCASFLAGS) by default, there's no need to explicitly set it here. Many of these dirs don't have .S files in the first place, so the rule doesn't even do anything. That can easily be seen when Makefile.in has no changes as a result. For the dirs with .S files, the custom rules are the same as the pattern .S.o rules, so this is a nice cleanup. The only dir that was adding extra flags (newlib/libc/machine/mn10300/) to the per-library setting can have it moved to the global AM_CCASFLAGS since the subdir only has one target. Although the setting just adds extra debugging flags, so maybe it should be deleted in general. There are a few dirs that we leave the redundant setting in place. This is to workaround an automake limitation in subdirs that support building with & w/out libtool: https://www.gnu.org/software/automake/manual/html_node/Objects-created-both-with-libtool-and-without.html
