patch for xfs/linux/getcwd.c

[Derrick J Brashear]

This is required to build on my RedHat 6.0/sparc system (with kernel
2.3.5)

  #include <stdio.h>

  #include <linux/stat.h>
  #include <errno.h>
  #include <dlfcn.h>

dev_t otherwise isn't defined in linux/stat.h

Also, for some reason, HAVE_INIT_MUTEX wasn't defined, and I had to define
it to get xfs_dev.c to build. When I get back I guess I'll look at why.
