while cross compiling for windows (config cross-win32.cbc), glib configure fails with this error:

checking for LIBFFI... no
configure: error: in `/home/nicola/cerbero/sources/windows_x86/glib-2.40.0':
configure: error: The pkg-config script could not be found or is too old.  Make sure it
is in your PATH or set the PKG_CONFIG environment variable to the full
path to pkg-config.

Alternatively, you may set the environment variables LIBFFI_CFLAGS
and LIBFFI_LIBS to avoid the need to call pkg-config.
See the pkg-config man page for more details.

To get pkg-config, see <http://pkg-config.freedesktop.org/>.
See `config.log' for more details

the fix is to link linux pkg-config in cerbero/build-tools/bin/

the pkg-config.exe created by cerbero seems not good. 

This happen with both master and 1.4.x branch
