[gobject-introspection] Pass in LDFLAGS to the dumper

[Johan Dahlin <johan src gnome org>]

commit e63866c2aea4338667a7e86c46f05864a991000d
Author: Johan Dahlin <johan gnome org>
Date:   Mon Apr 9 12:12:00 2012 -0300

    Pass in LDFLAGS to the dumper
    
    We should honor LDFLAGS environment variable set by the user,
    so options such as -Wl,--enable-new-dtags properly get passed to
    the linker when creating the dumper binary
