Cap end of relocations by the binary size.
Linkers like to insert some auxiliary sections between .rela.dyn and .bss_start. These sections don't make their way to the final binary, but reloc_rela still tries to relocate them, resulting in attempted read past the end of file.
When linking U-Boot with ld.lld, the STATIC_RELA feature (enabled by default on arm64) breaks the build. After this patch, U-Boot can be linked successfully with and without CONFIG_STATIC_RELA.

Thanks for the patch. Do you have any other changes for LLVM/LLDB support on arm64 platforms? I think I've had a few stumbles whenever I've tried and not been able to cycle back to them.
I think the patches I posted are enough to get U-Boot to build with LLVM LD for QEMU targets on arm64 and x86_64, but I have some other build problems to work through on physical device targets like rockchip.
Oddly, the arm64 binaries seem to be booting up (as far as we can see in a debugger), but there's no serial output, so there's still some work to do.
I'll keep upstreaming what we find. Our CI system is over here: https://ci.android.com/builds/branches/aosp_u-boot-mainline/grid? (using Clang but still ld.bfd for now)
