[Bug symtab/10542] New: 'set debug-file-directory' has no effect

[gdb+kisch at sesamstrasse dot dyndns dot tv]

I'm cross-debugging a remote target over a TCP-connection.
The executable to debug has a separated debug information file on the debug host.
The build-id method is used to link the executable to its debug info.
I'm trying to point gdb to the installation directory of the debug info files with
  set debug-file-directoy /path/to/debugfiles

This setting doesn't seem to have any effect (other than on "show debug-file-directory").

By starting the cross-gdb under strace, I can see that gdb searches the debugfiles at
/opt/crosstool/lib/debug (it was configured with --prefix=/opt/crosstool).
When I provide a symbolic link at that place, all the debuginfo files are found correctly.

So it seems that gdb is ignoring the debug-file-directory setting in my case.
