+src/xml: use preg-gen xmli18n_tmp.h if specified
+
+Ideally, the programs needed at build-time should be built with
+CC_FOR_BUILD, and not with CC_FOR_HOST.
+
+Unfortunately, this program wants to link against the gutenprint libs,
+so we would also need to build them with CC_FOR_HOST, that is build them
+twice, once for build, once for host.
+
+Instead, in the Buildroot context, we first build gutenprint for the build
+system, use that to generate the incriminated header, and then re-use that
+header to build the gutenprint for the host.
+
+It is not possible to have such constructs in Makefile.am:
+    ifeq ($(FOO),)
+    bar: bla
+        cat $< >$@
+    else
+    bar:
+        echo $(FOO) >$@
+    endif
+
+as autoreconf will yell loudly that there is an 'endif' without an 'if'.
+Sigh... :-(
