kbuild: hide error checker logs for V=1 builds
V=1 (verbose build) shows commands executed by Make, but it may cause
misunderstanding.
For example, the following command shows the outstanding error message.
$ make V=1 INSTALL_PATH=/tmp install
test -e include/generated/autoconf.h -a -e include/config/auto.conf || ( \
echo >&2; \
echo >&2 " ERROR: Kernel configuration is invalid."; \
echo >&2 " include/generated/autoconf.h or include/config/auto.conf are missing.";\
echo >&2 " Run 'make oldconfig && make prepare' on kernel src to fix it."; \
echo >&2 ; \
/bin/false)
unset sub_make_done; ./scripts/install.sh
It is not an error. Make just showed the recipe lines it has executed,
but people may think that 'make install' has failed.
Likewise, the combination of V=1 and O= shows confusing
"*** The source tree is not clean, please run 'make mrproper'".
Suppress such misleading logs.
