[PATCH 3/5] build: cross compile wayland-scanner

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

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

the wayland-scanner files are build with CC_FOR_BUILD instead CC like the other files.
CC_FOR_BUILD could be initialize by autotool but here it's still hard coded to "gcc"
