699e452654 Make CopyMem() and SetMem() be EFIAPI 
For wildly unknown reasons, EFI Boot Services includes CopyMem() and
SetMem() functions, and they are marked as EFIAPI functions.

This patch marks gnu-efi's CopyMem() and SetMem() as EFIAPI functions,
and makes their exposed API match the misguided nonsense in the EFI
spec, so that they can be used there in a test environment.

fb3b3f4c66 riscv64: ignore unknown relocs

- Make it actually work
- Split text/data/reloc/rodata sections
- Move hash sections to past end of image
  (un-needed in PE)
- Correct section & file alignment
- Correct image size
- rename .reloc to .areloc within ELF
  as only on ARM32 does this name cause
  it to be marked as REL and subsequently
  mistakenly added to RELSZ

Builds correctly & tested working in QEMU

fe76d597a9 Make ELF constructors/destructors work 
Since commit [4f8b339fac]
Simple EFI tools like for example t.c from the apps directory crash.

The reason seems to be a wrong null-pointer check in the
ctors()/dtors() functions in lib/entry.c.
