Yes it appears that this would apply to 2020.02.x since it is carry a
patch to add support glibc 2.33:

https://git.busybox.net/buildroot/tree/package/fakeroot/0006-libfakeroot.c-add-wrappers-for-new-glibc-2.33-symbol.patch?h=2020.02.x

I was looking at using buildroot on the bare minimum Alpine Linux
Docker container to help with finding issues with missing host
dependencies. Specifically looking at building on a non-glibc host
machine since Alpine is a musl based distro. Eventually my goal is to
have an autobuilder somewhere that actually builds with the minimum
package list which is listed in the buildroot manual.

Hopefully soon I can send a patch series which describes what issues
I've found and some patches for some missing host dependencies on some
packages.

Thanks,
