Introduce support/scripts/check-merged-usr.sh, a script that check if a
given path complies to the merged /usr requirements:
/
/bin -> usr/bin
/lib -> usr/lib
/sbin -> usr/sbin
/usr/bin/
/usr/lib/
/usr/sbin/
Use this script in skeleton-custom.mk instead of a bunch of variables
filled by $(shell ...) macros. The same script will be used to check
rootfs overlays, in a forthcoming change.
