So, where are you seeing this being an issue? My argument is that it
looks like a bug in bfd/gold, no in lld.

Gold produces a relocation to set the got entry to 42 + load_address.
BFD does the same for the got, but also changes

.quad foo

to contain 42 + load_address at runtime. That really looks like a bug,
if in a single assembly file we have

        .quad foo

both gas and MC produce a file with no relocations and just the value
42. Why should splitting the asm file in two change it?
