[Bug libc/5929] New: VALID_ELF_HEADER is not used for the executable

["drow at sources dot redhat dot com" <sourceware-bugzilla@sourceware.org>]

I'm working on a project that involves bumping the EI_ABIVERSION, since new
binaries require loader support.  We wanted a sensible error message when using
an old loader, but it doesn't work unless you run ld.so by hand:

$ /lib/ld.so.1 ./newtest.exe
./newtest.exe: error while loading shared libraries: ./newtest.exe: ELF file ABI
version invalid
$ ./newtest.exe
Segmentation fault (core dumped)

VALID_ELF_HEADER is only used when loading a new file; it is never applied to
the mapped executable when ld.so is the interpreter.
