[PATCH AUTOSEL 5.14 16/40] KVM: arm64: nvhe: Fix missing FORCE for hyp-reloc.S build rule

[Sasha Levin]

From: Zenghui Yu <yuzenghui at huawei.com>

[ Upstream commit a49b50a3c1c3226d26e1dd11e8b763f27e477623 ]

Add FORCE so that if_changed can detect the command line change.

We'll otherwise see a compilation warning since commit e1f86d7b4b2a
("kbuild: warn if FORCE is missing for if_changed(_dep,_rule) and
filechk").
