You need to look further down than this:

specifically for a line like
checking for library containing readline... -lreadline
which I imagine is reporting "no" for you.
The most usual cause of this sort of problem is forgetting to install the
devel support package for readline (on most Linuxen you need something
like readline-devel or readline-dev, not just the base readline package).
However, the devel package is usually what provides the .h files too,
so I'm a bit mystified as to what's wrong. Possibly, it'd be informative
to look into config.log to see what the underlying error report is for the
"library containing readline" test.
Also ...
denis ~/CProjects/postgres (REL_12_STABLE) $ pkg-config --libs
readline-L/usr/local/lib -lreadline
... you may need to say explicitly "--with-libraries=/usr/local/lib"
to get configure to look there for the library. The default linker
configuration on Linuxen is not that friendly to putting libraries
outside the system library directory.
