Buildroot will build the cross toolchain too unless you specify BR2_TOOLCHAIN_EXTERNAL, right? And likewise you can configure yocto to use an external toolchain

Buildroot will build the cross toolchain too unless you specify BR2_TOOLCHAIN_EXTERNAL, right? And likewise you can configure yocto to use an external toolchain. A lot of the byproducts are configurable. You could configure the system to not use an initramfs, use only an initramfs/squashfs, etc. It is a really great tool with great documentation. I agree that Yocto is a bit masochistic by comparison, but vendors like it because its primary purpose is to enable shitty vendor forks.
