echo 'main(){}'|gcc -g -x c -;./gdb -nx -ex start -ex 'p errno' ./a.out
Cannot find thread-local variables on this target
It happens for any variable marked by __thread when -lpthread is not used.
Fedora GDB has some hacks such as using `*__errno_location()' instead of `errno'.
The proper way would be glibc extension to support __thread variables even
without -lpthread mode as they are used not just for `errno'.
Draft patches included.

By Roland McGrath f2f, IIUC:
GDB can already iterate TIDs based on readdir(/proc/PID/task/).
Just TID->pthread_t translation and TLS variables access has currently no
equaivalent without libthread_db.
Therefore drop libthread_db, Roland proposes / will accept Python based
equivalent. Even drop libthread_db from gdbserver, Python can run at GDB (not
at gdbserver) as libthread_db-like-Python-implementation has no arch dependency
like libthread_db.so has, it can run from client GDB with small gdbserver
protocol extension packet for PTRACE_GET_THREAD_AREA and maybe some others.
