Subject: [bug#72136] [PATCH 2/2] gnu: bash-minimal: Don't support targets with no system.
Date: Tue, 16 Jul 2024 09:45:09 +0100

Since I believe bash-minimal will fail to build for these targets, this will
catch this early and display a clear message for both this package and
packages using it as an input.

* gnu/packages/base.scm (bash-minimal)[inputs]: Check the target if there is
one.
