make distclean and bash-4.4 - FYI

[Michael Felt]

Hi,

I finally got around to patching and packaging bash-4.4.23 and had to
run a "make distclean" because I had copied the old version and without
the make distclean make kept looking for "bashversion" in the old path
.../bash-4.4.19/bashversion

This is just FYI - I'll install yacc, which is what make is complaining
about now - but I also wonder if I could have avoided this by trying to
build oot (out of tree). Is this supported, or even recommended?

Thanks for a great product!

Michael
