[Buildroot] [PATCH 5/5] Makefile: fix out-of-tree builds with multiple targets with 'all'

From: "Yann E. MORIN" <yann.morin.1998 at free.fr>

For out-of-tree builds, this use-case fails to build:
    $ make clean all

This is because 'all' is filtered-out in the Makefile wrapper, since
the wrapper itself has a 'all' target.

The 'all' target is just the usual naming for the default target in a
Makefile. In fact, the first target is the default one, so we can name
it whatever we want.

Rename the Makefile wrapper 'all' target to avoid name-clashing.

Fixes #6644.
