`set remote exec-file' only instructs remote gdbserver in --multi mode.
It does not provide symbols to local GDB in any way.
Tested two cases, run on machine A, with remote host host1s which is also
mounted at /host1:
./gdb -nx -ex 'set sysroot /host1' -ex 'set debug-file-directory /host1/usr/lib/debug' -ex 'file /host1/home/jkratoch/t/1' -ex 'target remote host1s:1234' -ex 'b main' -ex c
./gdbserver :1234 /home/jkratoch/t/1
./gdb -nx -ex 'file /host1/home/jkratoch/t/1' -ex 'target extended-remote host1s:1234' -ex 'set sysroot /host1' -ex 'set remote exec-file /home/jkratoch/t/1' -ex start
./gdbserver --multi :1234
The `file' command provides the symbols for local GDB.
