Ick.  Couldn't we do this by #define XLOG in config.h.in, instead?
CFLAGS are horribly vulnerable to people overriding them with
make options.

I do recall that when I last tried to build with WAL, my attempt
to add #define XLOG to config.h failed --- but that indicates poor
coding practices elsewhere.  It *should* work to add or remove a
feature symbol in config.h.
