Yeah, environmental issues are indeed a developer's nightmare. I will
try to do something for the newcomers of riscv64 bpf. At present, I have
simply built a docker local vmtest environment [0] based on Bjorn's
riscv-cross-builder. We can directly run vmtest within this environment.
Hopefully it will help.

PS: Since the current rootfs of riscv64 is not in the INDEX, I simply
modified vmtest.sh to support local rootfs. And we can use it by:
```
PLATFORM=riscv64 CROSS_COMPILE=riscv64-linux-gnu- \
tools/testing/selftests/bpf/vmtest.sh -l /rootfs -- \
./test_progs -d \
\"$(cat tools/testing/selftests/bpf/DENYLIST.riscv64 \
| cut -d'#' -f1 \
| sed -e 's/^[[:space:]]*//' \
-e 's/[[:space:]]*$//' \
| tr -s '\n' ','\
)\"
```

Yeah, environmental issues are indeed a developer's nightmare. I will
try to do something for the newcomers of riscv64 bpf. At present, I have
simply built a docker local vmtest environment [0] based on Bjorn's
riscv-cross-builder. We can directly run vmtest within this environment.
Hopefully it will help.

PS: Since the current rootfs of riscv64 is not in the INDEX, I simply
modified vmtest.sh to support local rootfs. And we can use it by:
```
PLATFORM=riscv64 CROSS_COMPILE=riscv64-linux-gnu- \
tools/testing/selftests/bpf/vmtest.sh -l /rootfs -- \
./test_progs -d \
\"$(cat tools/testing/selftests/bpf/DENYLIST.riscv64 \
| cut -d'#' -f1 \
| sed -e 's/^[[:space:]]*//' \
-e 's/[[:space:]]*$//' \
| tr -s '\n' ','\
)\"
```
