[PATCH v3 0/2] [ld] Add library-related features for ld -r

[Eyal Itkin]

Introduce new CLI flags for "ld -r" to allow users to
transform it from a bundle of plain object-code files
into a library-like object-code file.

The full discussion about the format is available in
the generic-abi group that is responsible for the ELF
standard. Specifically, the summarized architecture can
be found here:
