It seems that for aarch64, unless we apply dynamic relocations to the location being relocated, we fail to boot.
As Fangrui notes: For dynamic relocations using the RELA format (readelf -Wr), GNU ld sets the initial content to r_addend; ld.lld doesn't do that by default (needs --apply-dynamic-relocs).
Otherwise .rodata appears to be full of NUL-bytes before relocation, causing crashes when trying to invoke the function pointers in init_sequence_f from initcall_run_list().

Applied to u-boot/master, thanks!
