I considered that but decided against it.  You can have exec-shield
disabled at configure time and enabled at compile time.  And besides,
if it is disabled and we treat it as enabled, the results are the same.

One idea would be to build Emacs normally with exec-shield off and then
turn it on to get exec-shield protection on the resulting Emacs binary.
Then your patch would make sense.  But it does not seem to work that way
as far as I can tell.
