Tue Nov 29 13:10:22 UTC 2022
commit: https://git.busybox.net/busybox/commit/?id=77216c368f3ae65c3a9fc504d28d3fadd46d6d8d
branch: https://git.busybox.net/busybox/commit/?id=refs/heads/master
Various tools are Linuxish and should thus only attempted to build on
Linux only. Some features are also Linux-only.
Also, libresolv is used on all GNU platforms, notably GNU/Hurd and
GNU/kfreeBSD.
