That’s true for object emission, but MC already depends on libObject, and
at least some of the more experimental parts of MC actually use it to read

However, - I believe nobody mentioned this - I think the point of having
ELF.h and friends in Support is that they’re intended to (more or less
exactly) match the headers provided by the system. Most of what’s there is
duplicated in a friendlier form (for ObjectFile-related stuff), or just to
match the LLVM style (notably Object/MachOFormat.h) in Object.
