What is intention of relocatable link and why it is called "partial linking" ? As far I understand intention is to speedup final link.
When we have multiple `.text` sections for example, then relocatable link merge them by name to output `.text`. Merging of sections helps to reduce amount of
input sections for latter final link.  We also merge SHT_REL[A] sections when doing that, it should probably help to speedup futher relocation processing as well.
As a last resort is also consistent with GNU linkers, it may be dangerous to deviate without solid reason as all kind of tools may rely on this behavior.
