[Buildroot] [git commit branch/next] core/out-of-tree: fix Makefile wrapper

[Thomas Petazzoni]

commit: http://git.buildroot.net/buildroot/commit/?id=6bae1ac5757f7dac2c906447502542bbb0cbdd62
branch: http://git.buildroot.net/buildroot/commit/?id=refs/heads/next

Commit 971faf8 (Makefile: fix out-of-tree builds with multiple targets
with 'all') renamed the default target to '_all' to avoid name-clashing.

In doing so, I forgot to also fix the instance in the .PHONY rule.

Fix that now.
