Would "coreutils-minimal" and "bash-minimal" suffice?
Or, more minimalistic,

  (parameterize ((%current-target-system #f))
    `(("bash" ,(canonical-package "bash")
      ("coreutils" ,(canonical-package "bash"))))

Or, more simply, let the inputs be (standard-packages).

These should probably be 'native-inputs' and not 'inputs'
for cross-compilation reasons.  Try
"./pre-inst-env guix build tosdr-chromium --target=aarch64-linux-gnu"
without transparant QEMU emulation, I think it will fail if these
inputs are in 'inputs' and not 'native-inputs'.
