I notice that if the platform's template doesn't set CFLAGS, then
configure will give you -g in CFLAGS whether you ask for it or not
(courtesy of AC_PROG_CC).  The --enable-debug configure switch thus does
not function as advertised.  If we are going to say that --enable-debug
isn't recommended for production, don't you think there should be a way
to turn it off?  Perhaps this means that all the template files should
force a setting of CFLAGS; or else that we should not use the stock
version of AC_PROG_CC.  Or maybe just set CFLAGS to empty right before
AC_PROG_CC?

This was sort of the idea, but I see some disappeared.

Probably best for now.  Eventually, I'd like it to look more like the
AC_PROG_CXX code, all in one place.  Right now the templates are a
safe-guard against trying to build on a platforms that's not supported at
all, but it should actually be possible to do just that, without shared
libraries maybe, and with the software-TAS that you implemented.  But ISTM
that we've covered the recent wave of new operating systems, so this is
not a pressing issue to me.
