gst-plugins-base-0.10.32: GST_DISABLE_XML=1 doesn't work in gstsubparse.c

[bcxa sz]

I think I have found the reason:

The current command line has the parameter --prefix=/usr. It is
correct if from the embedded system target point of view.

But when configure gst-plugins-base-0.10.32,

in gst-plugins-base-0.10.32/configure
==========================================================================
GST_CONFIGPATH=`$PKG_CONFIG --variable=includedir
gstreamer-0.10`"/gst/gstconfig.h"

It will try to find the includedir with pk-config
[root at fedora14 gst-plugins-base-0.10.32]# cat
/opt/STM/STLinux-2.4/devkit/sh4/target/usr/lib/pkgconfig/gstreamer-0.10.pc
prefix=/usr
exec_prefix=${prefix}
libdir=${exec_prefix}/lib
includedir=${prefix}/include/gstreamer-0.10
toolsdir=${exec_prefix}/bin
pluginsdir=${libdir}/gstreamer-0.10
datarootdir=${prefix}/share
datadir=${datarootdir}
girdir=${datadir}/gir-1.0
typelibdir=${libdir}/girepository-1.0

Name: GStreamer
Description: Streaming media framework
Requires: glib-2.0, gobject-2.0, gmodule-no-export-2.0, gthread-2.0, libxml-2.0
Version: 0.10.34
Libs: -L${libdir} -lgstreamer-0.10
Cflags: -I${includedir}
==============================================================================

But unfortunately, it will try to find the header file at host
/usr/include/gstreamer-0.10/gst/gstconfig.h. But it should find this
header file at:
===============================================================================
[root at fedora14 gst-plugins-base-0.10.32]# ls
/opt/STM/STLinux-2.4/devkit/sh4/target/usr/include/gstreamer-0.10/gst/gstconfig.h
/opt/STM/STLinux-2.4/devkit/sh4/target/usr/include/gstreamer-0.10/gst/gstconfig.h
===============================================================================

So I think this one should be gstreamer cross compile issue. Do you
have some suggestion to fix?
