How to add nodejs package?

[ConstantinFF]

I have been trying to add the nodejs package to the build.
But the build hangs without error.

From the menu nodejs dependencies are

nodejs needs a toolchain w/ C++, dynamic library, NPTL, gcc >= 7, wchar, host gcc >= 8

So

1. Inside Dockerfile I use FROM ubuntu:22.04 to have the latest gcc
2. Added also apt-get -q -y install file libbz2-dev, because they were required during the build
3. I clone and use latest code from https://github.com/buildroot/buildroot.git
4. Then I enabled toolchain with c++ from the menu
5. And the v86_defconfig config file that I got is:

BR2_x86_pentiumpro=y
BR2_PACKAGE_HOST_LINUX_HEADERS_CUSTOM_4_19=y
BR2_TOOLCHAIN_BUILDROOT_CXX=y
BR2_CCACHE=y
BR2_ROOTFS_OVERLAY="$(BR2_EXTERNAL_v86_PATH)/board/v86/rootfs_overlay/"
BR2_ROOTFS_POST_IMAGE_SCRIPT="$(BR2_EXTERNAL_v86_PATH)/board/v86/post-image.sh"
BR2_LINUX_KERNEL=y
BR2_LINUX_KERNEL_CUSTOM_VERSION=y
BR2_LINUX_KERNEL_CUSTOM_VERSION_VALUE="4.19.172"
BR2_LINUX_KERNEL_USE_CUSTOM_CONFIG=y
BR2_LINUX_KERNEL_CUSTOM_CONFIG_FILE="$(BR2_EXTERNAL_v86_PATH)/board/v86/linux.config"
BR2_PACKAGE_NODEJS=y
BR2_PACKAGE_NODEJS_NPM=y
BR2_PACKAGE_NANO=y
BR2_TARGET_ROOTFS_INITRAMFS=y
BR2_TARGET_ROOTFS_ISO9660=y
BR2_TARGET_SYSLINUX=y

The phase in which build stops and hangs is:
