Is there a way to workaround this?

ps. Perhaps, related to this FR #23

[vt-alt]

Btw, there is some powerpc support for linux, it is same as ppc64le?

#[cfg(not(any(
    target_arch = "powerpc",
    target_arch = "mips",
    target_arch = "x86",
    target_arch = "arm",
    target_arch = "x86_64",
    target_arch = "aarch64",
    target_arch = "riscv64"
)))]
