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().
Test: BUILD_CONFIG=u-boot/build.config.qemu.aarch64 ./build/build.sh && \
qemu-system-aarch64 -machine virt -bios \
out/u-boot-mainline/dist/u-boot.bin -display none -serial mon:stdio \
-nographic -cpu cortex-a53 -m 1024
