When compiling U-Boot with ld.lld as the linker, the helloworld EFI app example fails to link:
LD lib/efi_loader/helloworld_efi.so ld.lld: error: section: .dynamic is not contiguous with other relro sections
LLD will always create RELRO program header regardless of target emulation, whereas BFD may automatically disable it for unsupported targets. Add -znorelro to disable it explicitly in all cases.
