bug#1079: GNUstep port segfaults making autoloads on x86_64

[Glenn Morris]

Trying to bootstrap the GNUStep port on x86_64 GNU/Linux, it segfaults
making autoloads. The problem can be reduced to anything that tries to
set a variable, eg:

../src/bootstrap-emacs -batch --no-site-file \
  --eval '(setq make-backup-files nil)' 

Disclaimer: I know nothing about GNUStep, I just grabbed a tarball and
made a local installation of it.

Backtrace:


Program received signal SIGSEGV, Segmentation fault.
