[Devel] [PATCH hci-8.1 v2] configs: build with WERROR and KVM_WERROR, as RHEL does

[Konstantin Khorenko]

RHEL generates its configs in "make dist-srpm": the redhat/Makefile
dist-* targets export ENABLE_WERROR=1, and build_configs.sh then turns
CONFIG_WERROR, CONFIG_KVM_WERROR and CONFIG_OBJTOOL_WERROR on in every
config.

We call build_configs.sh directly, without ENABLE_WERROR, so the vz
kernel builds without -Werror and a new warning goes unnoticed.

We already have CONFIG_OBJTOOL_WERROR=y due to work on KLP, so set
CONFIG_WERROR and CONFIG_KVM_WERROR in custom-overrides/generic as well.
Like ENABLE_WERROR, they reach every flavor, the debug one included.

The um variant, the User Mode Linux KUnit kernel, does not build with
-Werror yet, so custom-overrides/generic/um/CONFIG_WERROR keeps it off
there.

Changes in v2:
- Name the um layer file that keeps WERROR off, not the generated
  kernel-um-rhel.config, which the kernel tree does not carry.
- Say the overrides reach every flavor, as ENABLE_WERROR does.
- Fix the target name: dist-srpm.
