adbd7ae7b6 Remove 64k gap on ARM32 
While binutils 2.25 incorrectly changed the page size
to 64K, the second part of that fix prevents the bug
anyways

c600b4e9a5 arm64 lds: move 64K gap to reloc

ELF where its mostly dynamic

deb8a7f267 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.

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.
