X-Git-Tag: v4.10-rc1~64^2~1

kbuild: fix scripts/adjust_autoksyms.sh* for the no modules case

When CONFIG_TRIM_UNUSED_KSYMS=y and no modules are actually selected,
the adjust_autoksyms.sh script fails with:

sed: can't read .tmp_versions/*.mod: No such file or directory

Let's cope with that case gracefully.
