gnu: emacs: Ignore empty XIM styles.
As of libx11 version 1.6.10, xim may be NULL, which causes a segmentation fault in the execution of ARRAYELTS. As a cautionary measure, we short-circuit this logic. * gnu/packages/patches/emacs-ignore-empty-xim-styles.patch: New file. * gnu/packages/emacs.scm (emacs emacs-next)[patches]: Use it. * gnu/local.mk: Register it.
