a patch to set ELF header flags for empty linker output files

[Nick Clifton]

Hi Jim,

: After considering the comments I've seen, I've decided that HJ's
: approach of ignoring empty (bfd->sections == NULL) object files is
: the better solution. 
: 
: So now the only question in my mind is whether we fix this just in
: the elfxx-ia64.c file similar to what was already done in the
: elf32-arm.h file, or whether we try to fix it for all targets with
: HJ's ldlang.c patch.  I can make the elfxx-ia64.c change on my own,
: but can't make the ldlang.c change unless others agree that it is a
: good idea. 

I have just approved a variation of H.J.'s patch, so I hope that this
problem will no longer occur.

Cheers
