[gdb] Autoloading symbols from remote target broken

[oold]

Description / Steps to reproduce the issue

Gdb used to be able to load shared library symbols automatically from the target. At the very least version 15.2-1 is able to do that, but the latest version (17.1-2 at this time) won't do it.

1. Launch gdbserver on remote Linux system.
2. gdb-multiarch
3. file [your-executable]
4. target remote [your-target-address]
5. show sysroot -> The current system root is "target:".
6. show auto-solib-add -> Autoloading of shared library symbols is on.
7. c
8. Break with Ctrl-C.
9. bt

The output implies it doesn't even attempt to load the solib symbols, neither while running nor while in break state.

Expected behavior

#0  0xb7fd6d09 in __kernel_vsyscall ()
#1  0xb7b4e29b in nanosleep () from target:/lib/i386-linux-gnu/libc.so.6
#2  0xb7b4e175 in sleep () from target:/lib/i386-linux-gnu/libc.so.6
#3  0x0948d0fa in [censored] at [censored]
#4  0x094b7aec in main (argc=1, argv=0xbffffd44) at [censored]

Actual behavior

#0  0xb7fd6d09 in __kernel_vsyscall ()
#1  0xb7b4e29b in ?? ()
