I CC:ed this to the binutils mailing list which is the proper
forum: it is the assembler that creates the relocations from the
.vtable_inherit and .vtable_entry pseudo-directives, and the
linker that handles them.

In short, they provide garbage-collect information for C++
virtual-function tables when -fvtable-gc is passed to gcc.
I'd recommend not to use that option; it does not function
properly.

These relocations should be gone by the time the executable
(with or without DSO:s) reach your loader.  It would be a bug if
they are still present there, assuming your loader expects a
fully linked (or dynamically linked) executable.  Do you see
these relocations in the executable?
