Hm, I don't find it that inconsistent to say that configure itself uses
CFLAGS but not EXTRA_CFLAGS (or whatever).

I personally do, and it's not a problem for me because I call configure
and everything from scripts anyway. But it's harder to to tell people
that. It's e.g. much easier to tell people that they should add one
argument to configure to specify -fno-omit-frame-pointer rather than
having to create Makefile.custom or something like that.
Makefile.custom doesn't, afaik, won't forward the cflags to PGXS built
extensions. Which then is annoying for flags like

If we'd persist COPT or PROFILE when specified for configure that'd work
for me as well.
