Hmm, try build nft but got error

# make -C tools/testing/selftests/wireguard/qemu/
make: Entering directory '/home/net/tools/testing/selftests/wireguard/qemu'
Building for x86_64-linux-musl using x86_64-redhat-linux
cd /home/net/tools/testing/selftests/wireguard/qemu/build/x86_64/nftables-1.0.9 && ./configure --prefix=/ --build=x86_64-redhat-linux --host=x86_64-linux-musl --enable-static --disable-shared

But I can config it manually like: ./configure --prefix=/ --build=x86_64-redhat-linux --host=x86_64-linux-musl --enable-static
--disable-shared correctly

Do you have any idea?

Thanks
