This series extends the ulib demo to ARM64 and RISC-V64, following the
existing x86 pattern. Each architecture re-links U-Boot with the example
objects so the demo's main() overrides the weak default. RISC-V requires
an additional prelink-riscv step to resolve GOT entries in the static
PIE binary.

EFI app builds are also supported on all three architectures, producing
a demo-app.efi binary that can boot under QEMU with UEFI firmware. A
build_api.py fix handles empty archives that appear in cross-compiled
EFI builds.

All new demos have pytests that boot under QEMU and verify the expected
output. A new 'localqemu' pytest marker skips these tests in lab mode,
since they launch their own QEMU rather than using the lab's managed
U-Boot instance.

This also updates the build-qemu script to support RISC-V.
