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.


Simon Glass (13):
  ulib: x86: Disable regparm when Rust examples are enabled
  disk: part_efi: Check the block size in part_test_efi()
  ulib: Extract common example build rules for demo
  ulib: Add Rust demo example
  ulib: x86: Add Rust demo for qemu-x86_64_nospl
  ulib: x86: Add 32-bit Rust target support
  ulib: x86: Enable Rust demo for qemu-x86
  ulib: riscv: Enable Rust demo for qemu-riscv64
  ulib: riscv: Add Rust demo test for qemu-riscv64
  ulib: x86: Enable Rust demo for efi-x86_app64
  ulib: arm64: Enable Rust demo for efi-arm_app64
  ulib: riscv: Enable Rust demo for efi-riscv_app64
  ulib: arm64: Enable Rust demo for qemu_arm64
