Subject: [PATCH AUTOSEL 5.14 32/99] powerpc: make the install target not depend on any build artifact

From: Sasha Levin <[email-masked]>
Date: Thu, 9 Sep 2021 20:14:51 -0400

From: Masahiro Yamada <[email-masked]>

[ 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.
