how to tailor gstreamer to embeded device?

I'm porting gstreamer(0.10.4) to an arm-linux
platform, but gstreamer is too big to port device. So
I want to reduce gstreamer and its dependencies(glib,
libxml) to minimum size.

Q1: how to tailor gstreamer core?
There are several subdirectories in gstreamer, but I
think I shouldn't enter all subdirs to run "make
install" , so which subdirs are mandantory? 
Are
"gst","libs","plugins"
and "pkgconfig" necessary?
What are the functions of those subdir?

Q2: how to tailor glib and libxml?
Gstreamer maybe use little function of glib and
libxml, but full installation of those is too huge. I
want to only install the minimum function set of glib
and libxml to meet gstreamer, what should I do?

I really appreciate your any answers and suggestions.

You really should look into them.  If you can't figure out
what's in
pkgconfig then you should understand what's in there before
you attempt
to do what you want to do.

gst is mandatory, though through compile options you can
disable some
features.  Run configure --help.

libs is going to be necessary for a lot of plugins.  plugins
contains
base functionality that you can choose to compile if you
want a
GStreamer that doesn't do much.

Basically, it's so easy to not install a whole lot of stuff
GStreamer
builds, and it depends on your actual application on what
you would want
to leave out.  None of us can say if for example you need to
have "tee"
or not.

You have to look at what you can disable in GLib yourself. 
A lot of
people have run GStreamer on ARM platforms, so this is
definately
doable.  If you mean to actually compile out GLib code,
you'll have to
experiment.  libxml can be disabled in the GStreamer build,
at the cost
of losing the registry caching.

Hope that helps,
Thomas
