hurd: add gnu_target pointer to fix thread API calls
Fixes
../../gdb/gnu-nat.c:1110:28: error: cannot convert ‘ptid_t’ to ‘process_stratum_target*’
1110 | thread_change_ptid (inferior_ptid, ptid);
and others related to 5b6d1e4fa ("Multi-target support")
gdb/ChangeLog:
* gnu-nat.h (gnu_target): New variable declaration.
* i386-gnu-nat.c (_initialize_i386gnu_nat): Initialize
gnu_target.
* gnu-nat.c (gnu_target): New variable.
(inf_validate_procs): Pass gnu_target to thread_change_ptid,
add_thread_silent, and add_thread calls.
(gnu_nat_target::create_inferior): Pass gnu_target to
add_thread_silent, thread_change_ptid call.
(gnu_nat_target::detach): Pass gnu_target to detach_inferior
call.
