make distclean breaks "later "configure && makes"", i.e., removes a file in distro that a build needs (cannot process parse.y)

[Michael Felt]

I can down the distribution, e.g. 
ftp://ftp.gnu.org/gnu/bash/bash-4.4.18.tar.gz, unpack it, goto base 
directory and run configure.

Thought I had reported this earlier, but guess not!

If after a successful build, I run "make distclean" - "./configure && 
make"  no longer works.

e.g.:
