glib2-shlibs.info clang fix

  The current glib2-shlibs.info in unstable fails to build under clang
due to errors of the form...

/bin/sh ../libtool  --tag=CC   --mode=compile gcc -DHAVE_CONFIG_H -I. -I..  -I..  -DG_LOG_DOMAIN=\"GLib\" -DG_DISABLE_CAST_CHECKS -DG_DISABLE_DEPRECATED -DGLIB_COMPILATION -DPCRE_STATIC -I/sw/include -DG_DISABLE_SINGLE_INCLUDES   -Os -Wall -c -o garray.lo garray.c

                                                                       ^

                                                         ^
./galiasdef.c:24:72: error: only weak aliases are supported on darwin
extern __typeof (g_array_insert_vals) g_array_insert_vals __attribute((alias("IA__g_array_insert_vals"), visibility("default")));

Only two solutions are possible. The first, patching glib/makegalias.pl and friends to emit
"weak, alias" rather than "alias" seems difficult to implement. The far simplier fix is to just
append --disable-visibility to ConfigureParams. Note that configure in glib reports...

  --disable-visibility    don't use ELF visibility attributes

The Mach-O object format doesn't support true alias in the object files ala ELF and 
the weak import that Geoff Keatting created is considered a partially functional hack.
So in the absence of any failures in glib, the --disable-visibility option seems wiser.
