Alan Modra notes about BFD:
The default linker emulation for an aarch64-linux ld.bfd is
-maarch64linux, the default for an aarch64-elf linker is
-maarch64elf. They are not equivalent. If you choose -maarch64elf
you get an emulation that doesn't support -z relro.
Should LLD not set the RELRO program header when targeting -maarch64elf to
better match compatibility with GNU BFD?
