@indntpoff is similar to @gotntpoff, but for use in position dependent code. While @gotntpoff resolves to GOT slot address relative to the
start of the GOT in the movl or addl instructions, @indntpoff resolves to the
absolute GOT slot address. ("ELF Handling For Thread-Local Storage", Ulrich Drepper).
Since this relocation resolves to the absolute GOT slot address it requires R_386_RELATIVE relocation for each place of using when linking shared library. Had to add Target::relocNeedsDynRelative() method that checks if a relocation requires R_386_RELATIVE relocation to be emited either.
