config.status exists and is executable as well.

~/s/e/e/s/e/build-gtk $ ls -ll config.status
ls -ll config.status
-rwxr-xr-x. 1 bhavin bhavin 81764 Jan  2 17:54 config.status

After running the "./config.status --recheck", it is running
"MAKE='/usr/bin/make' ./config.status", which in turn starts the build
again.

This is happening for Emacs 27.2 as well, the full build log is at the
following link, install starts at line number 10298:
https://kojipkgs.fedoraproject.org//packages/emacs/27.2/9.fc35/data/logs/x86_64/build.log

"." in this case is build directory build-gtk, which is inside the
source directory "emacs-28.0.90".

I was trying to figure out which files change in the source directory
after "make bootstrap" is run from build-nox. I'm not sure if that's a
correct thing to look at. I even tried to look at Makefile.in, but I'm not
sure where to look at and what to look at.

cd build-gtk/
./configure <for GTK>
make bootstrap
make
cd ..

~/s/e/e/s/emacs-28.0.90 $ ls -ll configure
-rwxr-xr-x. 1 bhavin bhavin 1007725 Jan  2 17:54 configure

cd build-nox/
./configure <for No-X>
make bootstrap
make

~/s/e/e/s/emacs-28.0.90 $ ls -ll configure
-rwxr-xr-x. 1 bhavin bhavin 1007725 Jan  2 18:14 configure

The timestamps on the configure, autom4te.cache directory, etc/refcards,
src/config.in, info (.info files), lisp (.elc files), doc directory are
updated at this point. The content is the same as it was after running
"make" from build-gtk directory (I'm tracking the content with Git).
