Error building kernel 5.11.14: references to /usr/lib64/gcc/x86_64-slackware-linux/10.2.0 , which isn't

After applying patch-5.11.13-14.xz then running make I got:

Code: ln -s /usr/lib64/gcc/x86_64-slackware-linux/10.3.0 /usr/lib64/gcc/x86_64-slackware-linux/10.2.0 cleared the error.

References to /usr/lib64/gcc/x86_64-slackware-linux/10.2.0 appear only in .cmd files, e.g., net/netfilter/.xt_length.mod.o.cmd
Where does it come from?
