[PATCH 6/6] Installed header hygiene (BZ#20366): Test of installed headers.

[Joseph Myers]

I'm seeing the new tests fail in misc/ for 32-bit x86, because of:

../sysdeps/unix/sysv/linux/x86/sys/elf.h:24:3: error: #warning "This header is obsolete; use <sys/procfs.h> instead." [-Werror=cpp]
 # warning "This header is obsolete; use <sys/procfs.h> instead."
   ^
cc1: all warnings being treated as errors
