and so emacs refuses to configure -- but if disable this test by doing:

  $ make ac_cv_file__proc_sys_kernel_exec_shield=no

Then Emacs configures and dumps just fine, despite not using `setarch'.

Does that machine have a /proc/sys/kernel/exec-shield-randomize file?


   $ cat /proc/sys/kernel/exec-shield-randomize

Incredible, I expected it to be zero.  Too bad there is a lack of
documentation on this feature.  I do know that both the compiler and
linker are involved, so maybe they have not been modified on that
machine?  Anyway, I'll try to come up with a better test where we
check the heap start address explicitly.
