0D: Instruction caching and better benchmark function.
The previous benchmark function had a few flaws. First of all, it wasn't
idiomatic Rust, because we used a loop construct that you would expect in C.
Revamped that by using an iterator. Also, the previous benchmark got heavily
optimized by the compiler, which unrolled the inner loop it into a huge sequence
of consecutive loads and stores, resulting in lots of instructions that needed
to be fetched from DRAM. Additionally, instruction caching was not turned on.

The new code compiles into two tight loops, fully leveraging the power of the I
and D caches, and providing an great showcase.

Correct linker issues
The new target is not automatically using PIC.

Need some linker script corrections for errors that were hiding
previously, so that we don't accidentally generate alignment
exceptions on bss size variables that cause the target to fail.

Use aarch64-unknown-none target in nightly 🎉
We have a generic target for writing bare-metal code
for 64-bit ARM architectures in upstream Rust now.

Use it to get rid of the fully custom target spec.

Don't invoke clippy via xargo
Despite invoking clippy with xargo, it wasnt actually using the custom
target, so we don't need xargo here for now...

The target argument was missing anyways. Using it throws an error.
Needs some more investigation.

Fix strange dockcross path changes
There were some strange changes to the aarch64 dockross image lately.
Looks like unintentional path changes. I'll adapt for now, but
hopefully this gets reverted to a sane state soon.
