faccessat.2, fchmodat.2, fchownat.2, fstatat.2, futimesat.2, linkat.2, mkdirat.2, mknodat.2, openat.2, readlinkat.2, renameat.2, symlinkat.2, unlinkat.2, utimensat.2, mkfifoat.3: Update feature test macro requirements 

Starting in glibc 2.10, defining _XOPEN_SOURCE >= 700,
or _POSIX_C_SOURCE >= 200809 exposes the declarations of
these functions.
