Yes, according to <http://hydra.nixos.org/build/2693322/contents/1> (the
build tree of a failed build), ‘$top_srcdir/gnulib/build-aux’ was indeed
r-xr-xr-x.

I’m not sure why that would be the case, nor why it would not
/systematically/ be a problem.

(Details on the bootstrap phase available at
<http://git.savannah.gnu.org/cgit/hydra-recipes.git/tree/coreutils/release.nix#n65>.)

Thanks,
Ludo’.
