Yep, services from the libc would be libdl-ed too. You would have to decide: either you use the machine code in a shared object, or you would statically link that machine code, but the idea is to make those explicit and different, not that current mess.

It means using the sysv x86_64 ABI entry point (which is basically a main()...).

The file format alone is useless, you need the ELF and ABI specs to know how to use properly the information defined by this very file format.
