Description
As noted in https://github.com/openwall/john/pull/4735#pullrequestreview-670278268, the output of ./configure --help has inconsistent capitalization.
On another note: When working on #4735 I noticed latest autoconf (2.71) wanted to update our configure.ac - some will happen semi automatically on request but even after that, some macros we use are deprecated. I simply downgraded autoconf to 2.69 (same as latest Ubuntu LTS use) instead, keeping that PR on topic, but at some point in time we'll probably want/need to do a 10,000 mile service on the whole ship wreck.

Research direction
Start with the capitalization inconsistencies in ./configure --help, then inspect configure.ac using the context from PR #4735. Check what autoconf 2.71 would update and which macros are deprecated, while considering the related work in #3566. Done means the configuration help is consistent and the project’s autoconf setup has been comprehensively updated.
