Emacs byte compilation failed

[chep]

I compile myself emacs master branch and update my packages very often

I can't install rtags with my aur package manager (archlinux):

Symbol’s value as variable is void: ivy-completing-read-handlers-alist

This patch fixed it but I'm not sure if it can be used as-is:
