Sounds like it would be better, if it works.

CONFIG_SITE needs to be set before configure runs, so you can't just set
it in configure.ac. Looks like what you would have to do is take the
contents of nt/mingw-cfg.site and insert them in configure.ac just after
the AC_INIT statement.

But it needs to be behind a test for mingw.
You can't use $opsys, because it isn't defined till later.

Maybe that test "$MSYSTEM" = "MINGW32" thing will work, though I don't
know what MSYSTEM is...

If you find something that looks like it should work, test it out with
and without configuring caching turned on, and see if work for you.
