We used to do something like this for the MinGW packages, since
-fstack-protector also causes a problem under Windows / MinGW
cross-compilation:

  CFLAGS="$RPM_OPT_FLAGS -fno-stack-protector" \
  ./configure [etc]

(example: http://hg.et.redhat.com/misc/fedora-mingw--devel/?fd=136ab7f25dc2;file=gnutls/mingw-gnutls.spec )

I should hasten to add that we don't do that any more, because we
defined our own %{_mingw32_cflags} macro so we'd have finer control.

Also, if anyone can fix -fstack-protector on Windows / MinGW, please
help!
