    # This package creates several scripts from
    # toosl/g-ir-tool-template.in.  In their original form these
    # scripts end up with a sbang line like
    #
    # `#!/usr/bin/env /path/to/spack/python`.
    #
    # These scripts are generated and then used as part of the build
    # (other packages also use the scripts after they've been
    # installed).
    #
    # The path to the spack python can become too long.  Because these
    # tools are used as part of the build, the normal hook that fixes
    # this problem can't help us.
    # This package fixes the problem in two steps:
    # - it rewrites the g-ir-tool-template so that its sbang line
    #   refers directly to spack's python (filter_file step below); and
    # - it patches the Makefile.in so that the generated Makefile has an
    #   extra sed expression in its TOOL_SUBSTITUTION that results in
    #   an `#!/bin/bash /path/to/spack/bin/sbang` unconditionally being
    #   inserted into the scripts as they're generated.
