FWIW 'config.status' is the log file generated by 'configure'.

You should provide, at the very least, the following information:
- the PostgreSQL version you are trying to build
- the environment you are trying to build it in

A very hand-wavy guess, but possibly your local "sed" installation is
not GNU sed?

I'm also wondering if the shell in use is nonstandard.  The configure
script would likely already have failed if you tried to run it with,
say, csh; but maybe more-subtly-incompatible shells could give rise
to this symptom.

You still didn't mention the platform/environment, but I guess from
the reference to -isysroot that it must be macOS (Darwin).  I further
guess that you're using Homebrew or MacPorts, because bare macOS
doesn't supply GNU sed.  That doesn't get us much further though;
plenty of Postgres developers use one or the other of those setups
without difficulty.

One idea that comes to mind is that you might be trying to build in
a directory path that contains spaces or other odd characters.
That's generally not well supported by Unix-based tooling.
However, I'm not sure how that'd lead to this particular failure.

The only other idea I have is that maybe you have some weird
Homebrew or MacPorts package installed that changes the behavior
of your shell.  I have no idea what that would be though.

FWIW, on my own Mac laptop, line 486 in config.status in a
current build looks like

    *\'*) ac_optarg=`$as_echo "$ac_optarg" | sed "s/'/'\\\\\\\\''/g"` ;;

which seems identical to what you reported.  So that takes some
steam out of the idea that the file was generated incorrectly
in your build, pointing more to the idea that your shell is not
reading it as-expected.
