[glib] Use -Bsymbolic-functions, drop g*alias PLT hackery

[Ryan Lortie <ryanl src gnome org>]

commit c9553af68f543113be41e6ae8dcdd9ee5e2267bc
Author: Ryan Lortie <desrt desrt ca>

    Use -Bsymbolic-functions, drop g*alias PLT hackery
    
    This is a minimal patch-out of the galias functionality.  We will do a
    release like this so that we can easily back it out if there are
    reported problems.
    
    A more substantial cleanup (mostly removing #includes from every file)
    will follow if there are no issues.
