ld: change --enable-new-dtags to only generate new dtags

Browse Source 
The "new" dtags options have been around for 14+ years, so there
shouldn't be a need to generate both new & old tags anymore.

@itemx --disable-new-dtags
This linker can create the new dynamic tags in ELF. But the older ELF
systems may not understand them. If you specify
@option{--enable-new-dtags}, the dynamic tags will be created as needed.
@option{--enable-new-dtags}, the new dynamic tags will be created as needed
and older dynamic tags will be omitted.
If you specify @option{--disable-new-dtags}, no new dynamic tags will be
created. By default, the new dynamic tags are not created. Note that
those options are only available for ELF systems.
