[PATCH 2/2] gas/as.c: compare device id
Different files may have the same inode number on different devices, for
example:
$ cat foo.c | gcc -x c - -o /dev/null
In this case, gcc will create a /tmp/foo.s, and if /tmp is a tmpfs, foo.s' ino
starts from a small number such 3, and /dev/null's ino is also small (e.g., 6),
so this is very likely to happen when there are many gcc's runs.
Compare device id will fix the problem.
