Well, supposedly patchelf produces such executables, although reading [1]
https://github.com/NixOS/patchelf/issues/153 and especially [2] gives me the
impression this might have been fixed in the meantime.

Another potential use case is Widevine CDM (obtainable from [3] and [4]), which
I intend to test with Firefox/Chromium and my glibc ABI compatibility hack
([5], think linuxpluginwrapper, but more reliable) to see how feasible that
approach actually is.

% env LD_PRELOAD=$PWD/libwidevinecdm.so true
ld-elf.so.1: .../libwidevinecdm.so: program header too large
% readelf -h libwidevinecdm.so 
...
  Start of program headers:          9300548 (bytes into file)
  Start of section headers:          9301776 (bytes into file)

Since this is a proprietary closed source library, I don't know how it was
built.

> Also, do you want same for binaries ?

Likely not.
