Unable to debug in hardware mode

Hi,
I am trying to debug libsgx_urts, however sgx-gdb is unable to find the symbols. Here are my build instructions:
``` make clean -j20 && make psw DEBUG=1 -j20 && make deb_psw_pkg DEBUG=1 -j20 && make deb_local_repo -j20 && apt update
apt-get remove libsgx-launch* libsgx-urts* libsgx-epid* libsgx-quote-ex* libsgx-dcap-ql* && apt-get install libsgx-launch-dbgsym libsgx-urts-dbgsym libsgx-epid-dbgsym libsgx-quote-ex-dbgsym libsgx-dcap-ql-dbgsym
```
I have checked my gdb and it does look for the files in "/usr/lib/dbg" and dpk -L does show the .debug file.

``` /usr/lib/debug/.build-id/14/4d4abb30e140eb8889caaf1a3a2878fd29e35c.debug ```

However, as you can see in the backtrace the debug symbols are still missing:

Any leads what might be going wrong here? I am using sdk 2.9
