It doesn't segfault for me, even when I build with -zcombreloc. I think -znocombreloc worked around bugs in now-obsolete versions of the GNU linker. See, for example:

https://lists.gnu.org/archive/html/bug-gnu-emacs/2004-02/msg00278.html
https://lists.gnu.org/archive/html/help-gnu-emacs/2003-05/msg00627.html

Looking at recent GCC documentation it appears that this old hack should not matter now, so I'm inclined to remove it, as in the proposed patch (attached), which I tested on Fedora 24 x86-64 but have not installed.
