 So I have looked into it now and tracked down `libthread_db' rather 
than GDB to be the component requiring PID retrieval from a core file 
for TLS access to work, and then only before glibc commit c579f48edba8 
("Remove cached PID/TID in clone"), which was first included in 2.25 
glibc release.

 Given I have been using recent glibc checkouts for MIPS verification I 
avoided the requirement, but I was indeed able to reproduce it natively 
with x86-64 and the system-supplied `libthread_db', and then with my 
MIPS environment as well, once I went with my glibc build back to commit 
c579f48edba8^.

 I will be adding a reference to said glibc commit when pushing your 2/3 
change.
