Yeah, G_SLICE affects glib and we just piggy-backed our own allocator
disable off that variable too for simplicity so both got disabled.

I think its probably worth keeping setting G_SLICE in the current
scripts and .mk files where we currently have it so that it continues
to disable the glib allocator for the gtk[2|3] and other pieces that
call glib stuff
