-Bsymbolic, I think? GLib uses this to speed up internal calls, instead of
the hacks with functions-having-two-names that it used to use.
With either solution, if you want to LD_PRELOAD (as for GLib's refdbg tool)
you have to have a second copy of GLib compiled to not do that, like
libglib2.0-refdbg in Debian.
