[cogl] build: Do not define "default" in m4

[Emmanuele Bassi <ebassi src gnome org>]

commit 38a728b45a3718d9db71c9dc46535ca188368627
Author: Emmanuele Bassi <ebassi linux intel com>

    build: Do not define "default" in m4
    
    The "default" m4 conflicts with one of libtool's internal symbols, one
    that is used to determine whether the -fPIC argument should be used;
    this breaks compilation onf 64bit platforms.
