Sorry, but no. I don't think the x86-64 -fno-pic case justifies changing the tradition that -no-pie/-pie does not change the layout (internal linker script). `-z lrodata-after-bss` is a common ground that we both can accept and it has its own merit to test two layouts for file-backed transparent huge pages.
