Whether or not it is simple is irrelevant to the present patch, which is 
explicitly basic infrastructure on which further patches can build as 
necessary.  I do not think the present patch loses any features presently 
in binutils, and it provides the features required for my immediate uses 
of the feature (Power and MIPS floating-point ABI tagging).  If you wish 
to add further features on top of it, please do so in subsequent patches.

ld can use the section view of the file when checking for consistency with 
a shared library, without need to handle a new program segment.
