After I had a look at FreeBSD rtld code...
The problem is that FreeBSD rtld code is now quite different from our
ld.elf_so, although they were very similar long time ago. To reduce
pain of modifying it so that it has support for other platforms not
in the FreeBSD rtld, I'd like to propose to import only necessary
features into our ld.elf_so, not rtld itself. I think I can do at
least "SymCache" C++ optimization part myself until the end of this
