Move the platform-dependent logic that sets CFLAGS_SL from src/makefiles/Makefile.foo to src/template/foo, so that the value is determined at configure time and thus is available while running configure's tests. On a couple of platforms this might save a few microseconds of build time by eliminating a test that make otherwise has to do over and over. Otherwise it's pretty much a wash for build purposes; in particular, this makes no difference to anyone who might be overriding CFLAGS_SL via a make option. This patch in itself does nothing with the value and thus should not change any behavior, though you'll probably have to re-run configure to get a correctly updated Makefile.global. We'll use the new configure variable in a follow-on patch. Per gripe from Kyotaro Horiguchi. Back-patch to all supported branches, because the follow-on patch is a portability bug fix.
