Some systems do not install binaries to /bin, and therefore do not provide /bin/bash. This includes Linux distros which intentionally avoid implementing the Filesystem Hierarchy Standard (FHS), such as NixOS and Guix System. The recipies inside arch/um/Makefile don't require top-level Bash to build, and setting "SHELL" to "bash" makes Make pick the Bash executable from the environment, hence this patch. Changes since last roll: - Rebase onto a more recent commit on the master branch. - Remove a dangling in-text citation from the change log. - Reword the change log.
