Bjørn Forsman acc76a6ef9 Change /bin/bash shebangs into /usr/bin/env bash
Not all systems have /bin/bash (e.g. NixOS[1] doesn't). Buildroot
already uses /usr/bin/env shebangs for other interpreters (perl,
python), so why not bash?

This changes only the shebangs used by Buildroot itself; stuff installed
to the target system is left unchanged.

With this applied I can run Buildroot unmodified on NixOS.
