This is mainly useful for myself to merge pull requests like https://github.com/bitcoin-core/qa-assets/pull/4

I thought it wouldn't hurt to share the code.

Also remove the --disable-ccache from the docs to speed up builds when developing fuzzers.

This looks like leftover debugging.

MarcoFalke commented at 6:38 PM on March 13, 2020:

Merging is currently a manual operation, so I like the extra verbosity. Happy to remove if you have strong feelings about this.

If it's intentional, no problem; It just seemed written strangely as a log message, so I wanted to make sure it wasn't a leftover.
