Patch for libc/sysdeps/linux/mips/bits/mman.h

[Joseph S. Myers]

The MIPS <bits/mman.h> header is missing definitions of POSIX_MADV_* 
(present on other targets), as shown up by Open POSIX testing.  This 
patch, corresponding to one submitted for glibc 
<http://sources.redhat.com/ml/libc-ports/2006-04/msg00034.html>, adds the 
missing definitions.
