Compilation successfully! I plan to close this issue as fixed, and send this
patch to the OpenWrt project (named `007-fix-null-dereference-with-lto.patch`
in the attachments)
linker prints some warnings, looks like it's about the libdw component:

Also a full log after compilation, named `elfutils-success.log` is provided in

Thanks for your excellent work! I appreciate your kindness and generous help.
