[PATCH 2/5] build: break the dependecy between wayland-scanner and libwayland-util.la

[mchalain [marc.chalain@gmail.com]]

From: mchalain <marc.chalain at gmail.com>

libwayland-util.la is used by other wayland libraries and it contains more functions useless for wayland-scanner.
To build wayland-scanner without dependency with wayland libraries, the wayland-util.c is only linked to wayland-scanner.
Autotool doesn't allow to compile a file twice, but it's possible to change the name of the target file. wayland-util.c generates scanner-wayland-util.o .
