Bash 5 compilation issue

[Ergus]

Hi bash5 is out in distributions like arch linux, but the regex to check the version in crosstool-NG/configure.ac does not include it. This fixes the issue:

diff --git a/configure.ac b/configure.ac

crosstool-NG/configure.ac is part of crosstool-NG project, not this project.

Now that crosstool-NG has been updated, can the submodule commit referencing it be updated to pull in the change?

Yes, please, I was trying to figure out why it wasn't building for me.

@pfalcon yes I agree with @nashley, could you please do so?
