sh_offset(.bss) has a bug: sh_addr%maxpagesize != sh_offset%maxpagesize.
This was fixed by https://reviews.llvm.org/D66658

This was fixed by https://reviews.llvm.org/D71035 (included in lld 10.0.0)

At the previous commit 9e119ad69df716b728c8d190ac808fa509818c1e, llvm-objcopy
still produced 64k output.
