BASH_ENV already has a defined meaning that conflicts with your
suggestion; read 'man bash' once more.

But bash does have the -O and +O command line option for choosing prior to
script execution what any shopt setting should be.  In other words,

bash -O igncr script_with_cr_lf

will guarantee execution of the script with \r ignored (at least, up until
the script does something to change that shopt).
