It's the same problem with cpio.h:

Testing <cpio.h>
----------------
  Checking whether <cpio.h> is available... FAIL
    Header <cpio.h> not available  Compiler message:
    -----------------------------------------------------------------------
    /home/carlos/build/glibc/conform/POSIX2008/cpio.h/scratch/cpio.h-test.c:1:18: fatal error: cpio.h: No such file or directory
     #include <cpio.h>
                      ^
    compilation terminated.
    -----------------------------------------------------------------------

  Checking the namespace of "cpio.h"... SKIP


----------------------------------------------------------------------------
  Total number of tests   :    1
  Number of failed tests  :    1 (100%)
  Number of skipped tests :    1 (100%)

That is to say a failure to find the header.

I'll have to look into this.

I don't know why this would be radically different from whatever environment
you're using though. 

Cheers,
Carlos.
