Select CFLAGS_SL at configure time, not in platform-specific Makefiles.
Move the platform-dependent logic that sets CFLAGS_SL fromsrc/makefiles/Makefile.foo to src/template/foo, so that the valueis determined at configure time and thus is available while runningconfigure's tests.On a couple of platforms this might save a few microseconds of buildtime 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_SLvia a make option.This patch in itself does nothing with the value and thus should notchange any behavior, though you'll probably have to re-run configureto get a correctly updated Makefile.global. We'll use the newconfigure 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.Discussion:https://postgr.es/m/20191010.144533.263180400.horikyota.ntt@gmail.com
