Callum Farmer fb3b3f4c66 riscv64: ignore unknown relocs 
Sometimes ld emits relocs such as R_RISCV_64 for unwind symbols
these don't need to be handled yet so just can be skipped otherwise
the binary will never load

- 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

Builds correctly but untested

Callum Farmer eadee98bf0 ARM32: fix image 
- 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

Nigel Croxon bbc2b528e0 Revert "Make ELF constructors/destructors work"

Nigel Croxon 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.
