rename elfedits

In the previous commit, I had not properly removed prebuilts/gcc/ from
manifests upstream.  This failed presubmits in aosp/1441815.

The prefix for the elfedit binaries is indeed CROSS_COMPILE, but for
Android common kernels, that's the tool prefix, not the target triple
(CLANG_TRIPLE).  It seems I myself continue to mix these up.

platform/prebuilts/gas/linux-x86

This repository exists as a temporary repository for containing copies of prebuilt binaries of GNU as (the assembler), copied from

  1. https://android.googlesource.com/platform/prebuilts/gcc/linux-x86/x86/x86_64-linux-android-4.9/
  2. https://android.googlesource.com/platform/prebuilts/gcc/linux-x86/arm/arm-linux-androideabi-4.9/
  3. https://android.googlesource.com/platform/prebuilts/gcc/linux-x86/aarch64/aarch64-linux-android-4.9/

It only contains binaries for linux-x86 host, which can target x86 and ARM (32b and 64b variants).

It will be used to minimize Android Common Kernel dependencies on GNU binutils for the “S” release, as part of: https://android.googlesource.com/platform/prebuilts/clang/host/linux-x86/+/master/BINUTILS_KERNEL_DEPRECATION.md (The creation of this repository is step 4).

If all goes well, then these binaries may never end up being used. Their existence is a hedge in the case of updates to kernel sources requiring the fallback to GNU as instead of Clang's integrated assembler.

As of Sept 29 2020, https://www.kernel.org/doc/html/latest/process/changes.html for a v5.9-rc7 Linux kernel requires binutils version 2.23 or newer. These binaries are based off of 2.27.0.20170315.
