From: Masahiro Yamada <masahiroy@kernel.org>

[ Upstream commit 9bef456b20581e630ef9a13555ca04fed65a859d ]

The install target should not depend on any build artifact.

The reason is explained in commit 19514fc665ff ("arm, kbuild: make
"make install" not depend on vmlinux").

Change the PowerPC installation code in a similar way.
