rdm reports errors on archlinux arm64 and unable to find symbols

Describe the bug
Hey, thanks for the great project first.
Recently I moved my workspace to an arm64 kvm but rtags seems not working.
It runs fine on small project excluding the Linux kernel.

To Reproduce
Steps to reproduce the behavior:

1. git clone https://github.com/torvalds/linux && cd linux && git checkout v5.13-rc1
2. copy .config to linux directory
3. bear -- make -j8
4. rc -J .
5. rc -F $some_symbol

Expected behavior
A clear and concise description of what you expected to happen.

Reminder: call bear -- make CC=clang -j8 to compile linux then rtags works.
