+commit 5707e9db9c398d311defc80c5b7822c9a07ead60

+    hurd: Add multilib paths for gnu-x86_64
+    
+    We need the multilib paths in gcc to find e.g. glibc crt files on
+    Debian.  This is essentially based on t-linux64 version.
+    
+    gcc/ChangeLog:
+    
+            * config/i386/t-gnu64: New file.
+            * config.gcc [x86_64-*-gnu*]: Add i386/t-gnu64 to
+            tmake_file.

+
+    hurd: Ad default-pie and static-pie support
+    
+    This fixes the Hurd spec in the default-pie case, and adds static-pie
+    support.
+    
+    gcc/ChangeLog:
+    
+            * config/i386/gnu.h: Use PIE_SPEC, add static-pie case.
+            * config/i386/gnu64.h: Use PIE_SPEC, add static-pie case.

+Hurd: comment PF_LINK/AF_LINK defines

+Comment out the PF_LINK and AF_LINK defines, since they are usually associated
+with struct sockaddr_dl, which is not available on Hurd.

+Subject: [PATCH] bits_atomic.h_multiple_threads
+
+TODO.  bits/atomic.h for GNU Hurd.
+    
+Source: Debian, eglibc-2.10/debian/patches/hurd-i386/local-atomic-no-multiple_threads.diff, r3536.
+Author: Samuel Thibault <samuel.thibault@ens-lyon.org>
+
+We always at least start the sigthread anyway.  For now, let's avoid forking
+the file (which would mean having to maintain it).
+
+Need to override sysdeps/i386/i486/bits/atomic.h to remove Linuxisms.
