Because you end up with a dynamic R_386_GLOB_DAT relocation, so need to
allow for that. See the "+ REL R_386_GLOB_DAT" in
sysdeps/unix/sysv/linux/i386/localplt.data to allow for that (of course,
such annotations naming an architecture-specific relocation require an
architecture-specific localplt.data file, not an OS-specific but
architecture-independent one such as you presently have for Hurd).
