Details:

libtool uses hard links for locking purposes. It links
itself into the directory of libtooled project. This wouldn't
work if the libtool and the project are on different volumes.
Example patch on ltmain.* files:

@@ -794,7 +794,7 @@
     # Lock this critical section if it is needed
     # We use this script file to make the link, it avoids creating a new
file
     if test "$need_locks" = yes; then
-      until $run ln "$progpath" "$lockfile" 2>/dev/null; do
+      until $run $LN_S "$progpath" "$lockfile" 2>/dev/null; do
        $show "Waiting for $lockfile to be removed"
        sleep 2
       done
