PATCH 1/1 xlib_libX11: fix compilation of makekeys

xlib_libX11 builds a makekeys executable for the host, but uses the targets X11_CFLAGS. This leads to build failures like
http://autobuild.buildroot.net/results/411eb3aefea859a7e31986a44acd50b475f174cb/

This problem was introduced by the version bump, because then also the AUTORECONF was removed so the existing fix didn't work anymore.

As a slightly cleaner solution, just remove X11_CFLAGS from the Makefile. We know we don't need it, because the X11 stuff is in $(HOST_DIR)/usr/include which is already in HOST_CFLAGS.

Hasn't this broken the xlib-x11 build? See
http://autobuild.buildroot.org/results/6a5a16f901215acca06cb7a89f7d7fb0bc1741af/build-end.log.

It is including a host header (Xos.h) which itself includes target headers. Sounds really wrong.

Indeed, and this patch fixes that. It's a different symptom of the same
error: makekeys is a host binary, but it's built with target CFLAGS (X11_CFLAGS = -I$(STAGING_DIR)/usr/include). This will barf in surprising ways.

(That is, unless you have an autobuilder that runs against a git tree that
has already integrated this patch; if that is the case, then I made a mistake somewhere.)

Regards,
Arnout

Aaah, your patch hasn't been integrated yet. My bad. Peter, could you merge Arnout's patch then?

Thanks,

Thomas
