Scott Wood 8137af19e7 arm64: Add tool to statically apply RELA relocations
ARM64 uses the newer RELA-style relocations rather than the older REL.
RELA relocations have an addend in the relocation struct, rather than
expecting the loader to read a value from the location to be updated.

While this is beneficial for ordinary program loading, it's problematic
for U-Boot because the location to be updated starts out with zero,
rather than a pre-relocation value.  Since we need to be able to run C
code before relocation, we need a tool to apply the relocations at
build time.

In theory this tool is applicable to other newer architectures (mainly
64-bit), but currently the only relocations it supports are for arm64,
and it assumes a 64-bit little-endian target.  If the latter limitation
is ever to be changed, we'll need a way to tell the tool what format
the image is in.  Eventually this may be replaced by a tool that uses
libelf or similar and operates directly on the ELF file.  I've written
some code for such an approach but libelf does not make it easy to poke
addresses by memory address (rather than by section), and I was
hesitant to write code to manually parse the program headers and do the
update outside of libelf (or to iterate over sections) -- especially
since it wouldn't get test coverage on things like binaries with
multiple PT_LOAD segments.  This should be good enough for now to let
the manual relocation stuff be removed from the arm64 patches.
