OK, I found what is wrong.

gcc-4.8.5-44.el7.x86_64
devtoolset-8-gcc-8.3.1-3.2.el7.x86_64

I'm using CentOS 7, and using gcc from devtoolset for building kernels.
Although .config says

CONFIG_CC_VERSION_TEXT="gcc (GCC) 8.3.1 20190311 (Red Hat 8.3.1-3)"

, the distribution's default gcc

GCC: (GNU) 4.8.5 20150623 (Red Hat 4.8.5-44)

is used for building tools/objtool/exec-cmd.o etc. Explicitly adding

export PATH=/opt/rh/devtoolset-8/root/usr/bin:$PATH

solved this problem.

It would be nice if Makefile can also check gcc version used for building tools.
