Could you add the motivation of this change
(as Nikolaus reported) ?
Without the reason recorded in git-log,
somebody may wonder why this commit is useful.

BTW, if System.map is missing, depmod is silently skipped.
I think if System.map is missing, a user is doing something wrong,
but you could do like this:
$ make mrproper
[snip]
$ make defconfig
[snip]
$ make modules
[snip]
$ make modules_install
INSTALL drivers/thermal/x86_pkg_temp_thermal.ko

DEPMOD 4.18.0+
The log looks like all the process went well,
but depmod is actually skipped because System.map is
generated by "make vmlinux"
What do you think we should do about this case?
Skip depmod silently?
Make it fail?
Print noisy warning like missing depmod case?

This is probably in the kmod package.
