Bug 383738

The checks for these two programs passed in 2.1 and I believe in early 2.9 versions but not at the moment.
Each check finds the binary in the expected place, but the Simple Test fails.

I regularly upgrade my TeX Live distribution, so it's possible that the behaviour changed there but I just didn't notice at the time. I'm currently using the 2017 distribution.

If I manually execute the same commands from the Simple Test, the BibTeX command seems to fail due to the filename extension:

jeremy@EliteChook2 ~/projects/kile/src/test $ latex test_bib.tex

If I run "bibtex test_bib", it works.
Is that weird? Does that seems like the behaviour of bibtex changed? Because it looks like the configtest code hasn't changed materially in a long time.

I don't know why MakeIndex is failing, it returns 0 when I run it manually.
