Error trying to upgrade to 1.6.0

Hi,

I cannot build my Android project with the new gstreamer 1.6.0 release (I was using 1.4.3), using NDK r17c. I get the following errors:
  /home/nirbheek/projects/repos/gst/cerbero.git/build/sources/android_universal/armv7/glib-2.56.1/_builddir/../glib/gconvert.c:175: error: undefined reference to 'libiconv_open'

  clang++: error: linker command failed with exit code 1 (use -v to see invocation)

Can someone please help ?
Thanks.
