Remove upstream ARC and Xtensa patches.
Keep all other patches from binutils 2.31.1.
See the release note:
https://sourceware.org/ml/binutils/2019-02/msg00010.html
While testing the Binutils 2.32 version bump, the Qemu xtensa
defconfig (that was using a kernel 4.16) needed to be updated with a
patch [1] from kernel 4.19 otherwise the kernel doesn't boot with
binutils 2.32 [2].
Since then, all Qemu defconfig has been updated by commit [3] to use a
4.19 kernel, so the issue no longer exists.
All other architectures has been tested using toolchain-builder [4].
