I don't think the conditionals are really needed. What compilers are we
talking about? Basically, this requires:
(a) A compiler that provides a C++ runtime that requires the old calls
and can't use the program header.
(b) A compiler that doesn't use a custom version of crtbegin/crtend
anyway.

I believe that GCC always installs it own copy if build from source and
I am not aware of any other C++ compiler that fulfills (a). So I think
it is good enough to keep them documented as obsolete and no longer
supported.
