From: Simon Glass <simon.glass@canonical.com> The Rust ulib demo currently only builds on x86_64. This series extends it to x86 (32-bit), RISC-V 64 and ARM64, for both QEMU and EFI targets. Along the way it fixes a rustc jobserver warning (MAKEFLAGS leak) and a linker crash on aarch64 caused by a Rust null-pointer-dereference check emitting an undefined panic symbol.
