I don't know whether or not it'll work, but you might try removing
thread-db.o (and also perhaps proc-service.o) from the NATDEPFILES
line in config/i386/linux.mh.  This will leave you with just the LWP
layer.

lin-thread.c and linux-thread.c are deprecated (and should be made
obsolete).  You should be using lin-lwp.c, thread-db.c, and
proc-service.c for thread debugging now.  (As noted above, it may
be the case that the lwp layer will work by itself, but I haven't
tried it recently on linux...)
