The RISC-V port is MACHINE=riscv MACHINE_ARCH=riscv64 (c.f.
MACHINE=arm64 MACHINE_ARCH=aarch64 or MACHINE=powerpc
MACHINE_ARCH=powerpc64), so you need to give -a riscv.riscv64 to
poudriere rather than -a riscv64 (which is shorthand for -a
riscv64.riscv64), unlike amd64 where MACHINE=MACHINE_ARCH=amd64 so the
shorthand works. Building src is smarter about inferring one from the
other rather than defaulting to them being the same, but poudriere is
not.
