This reverts commit 8b3a31f923.
commit 8c80bd08b7
("build-support/cc-wrapper: pass in non-existent --sysroot= to untangle
from libc") was reverted. We can drop the workaround.
`ubootTools` build broke after https://github.com/NixOS/nixpkgs/pull/210004
where we started dropping default libc include path and switched to
`-idirafter` way of specifying libc headers.
Unfortunately the way it's implemented it injects -idirafter after
user's flags, not before. That allows users to inject their paths before
libc include paths, not after (as it would notmally happen).
The change works it around for u-boot by pulling -idirafter libc flags
before user's flags.
Add a new U-boot flavor for LibreComputer's AML-S905X-CC (Le Potato).
Board's SoC is based on Trusted Firmware-A architecture and needs extra
closed-source early bootloaders to be combined with U-boot in order to
boot properly, similar to Odroid-C2 board.
Proprietary blobs and related tooling are fetched from
github.com/LibreELEC/amlogic-boot-fip and used in postBuild along with
build output.

Provide a (yet unmerged) patch that allows NixOS to boot correctly on
new Pi4 boards using the BCM2711C0 SoC. Revert this when the patch is
available in mainline U-Boot.

This adds support for the Radxa Rock Pi 4 board which is based on
RK3399. The u-boot outputs from the introduced build are suitable to
build a generic image for the Rock Pi 4 by setting the following in a
custom build of $nixpkgs/nixos/modules/installer/cd-dvd/sd-image-aarch64.nix:
```
sdImage.postBuildCommands = ''
dd if=${pkgs.ubootRockPi4}/idbloader.img of=$img seek=64 conv=notrunc
dd if=${pkgs.ubootROckPi4}/u-boot.itb of=$img seek=16384 conv=notrunc
'';
```
