Maybe I'm missing something obvious.  The link will be created to point
at /export/gnu/src/gdb/gdb/gdb/doc/all-cfg.texi.  Whether
../../../../../import/gdb/src/gdb/doc/all-cfg.texi exists from that
directory does not matter.  It will be resolved from the directory
containing the second symlink.

Otherwise relative symlinks would never be useful.
