Document where to look for config.log on installation failure

[alexeyr-ci1]

When installation fails, the error says something like

configure: error: readline library not found
If you have readline already installed, see config.log for details on the
failure.  It is possible the compiler isn't looking in the proper directory.
Use --without-readline to disable readline support.

The problem is that I do have readline installed (both with Homebrew and with apt-get).

I found the correct config.log file in /tmp/tmp.Egrr7jiygn/postgresql-15.1/config.log (after some figuring out due to previous failing errors). Is it possible to do one of following (in order of my preference)?

1. Give the full path to config.log in the error message (probably not, I assume it comes from Postgres itself);
2. Include the build directory under /tmp in a separate message;
3. Mention how to find the file in README.

Since I haven't experienced what you're experiencing, I am not in a great position to document it. If you want to add a troubleshooting section to the docs though, or figure out a way to print out the tmp directory location, I'd be totally fine with that.

https://github.com/smashedtoatoms/asdf-postgres/pull/73 should also solve this issue.

I just merged @stanhu's PR. @alexeyr-ci1, can you update to the latest asdf-postgres and try again and let us know if it behaves as expected?
