xlib_libXt: fix build issues

The .mk file was hacking the CC_FOR_BUILD value so that
$(STAGING_DIR)/usr/include is added to the include path. This is not
correct since $(STAGING_DIR) contains target stuff, not host
stuff. The correct fix is to add a dependency on host-xproto_xproto,
which will install the needed headers in $(HOST_DIR)/usr/include.

In addition to that, a patch is added to make xlib_libXt build system
behave properly in the cross-compilation case, where the makestrs tool
needs to be built on the host as part of the compilation process. This
was working before because of our quirky TARGET_CONFIGURE_OPTS, but
those are going to be fixed in a future commit.

+Subject: [PATCH] fix cross-compile again
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+makestrs should always be built for the target arch. When cross-compiling,
+create a native version "xmakestrs" which will always be noinst, and use it
+to generate the other sources.
+
+This avoids installing a makestrs built for the wrong arch.
+
+Based on this patch :
+http://overlays.gentoo.org/proj/embedded/browser/openmoko/trunk/openmoko-target/x11-libs/libXt/files/libXt-1.0.7-crosscompile-makestr.patch
