+[patch]: configure: add --with-keysymdef argument for cross compilation
+
+Based on a similar patch from Openembedded.
+
+The libX11 configure script hardcodes the location to keysymdef.h as
+<prefix>/include/X11/keysymdef.h, which is fine for native compilation,
+but breaks with cross compilation as that directory is a location on
+the target, not the build host.
+
+Fix it by providing an explicit --with-keysymdef=<full-path-to-file>.
