Makefile: apply dynamic relocations for LLD
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().
