I can confirm that it makes fork() work again, so Debian Etch, Lenny,
Sid work on ARM inside a chroot running with QEMU (e.g. by running a
shell inside the chroot).

Nevertheless, Aurelien promised me that he or the author will take a
look into svn commit 6095, because the case that CONFIG_USER_ONLY is
defined and USE_NPTL cause the function gdbserver_fork() to be not
defined inside gdbstub.c, thus causing a compilation error. Also, the
question is open if gdb works and was tested in user mode with more than
one threads at all (on the other hand, the makes sense only if yes).
