Thanks Corona for pointing that out.
Which is one example of the tricks I am trying to get familiar with, but it works.
The examples were from the LQ forum while I was self-study the Makefile skill. I believe the original author left the spaces and . (dots) in the string to show the idea of dependency in Makefile. I posted here to get expert direction about my confusion on the target of Makefile (temp.txt, in this case). By the way, I am aware this is ABC for computer science, not my subject. Thanks anyway.

CREATE_MAKEFILE [FIXME: manual] CREATE_MAKEFILE
NAME
create_makefile - Creates Makefile.in and Makefile from a Makefile.am
SYNOPSIS
create_makefile [relativepath/Makefile] [relativepath]
DESCRIPTION
create_makefile creates the Makefile.in and Makefile in a subdirectory containing a Makefile.am. This script saves time compared to
re-running configure completely
Note that you must supply the path to the desired MakefileMakefile.am (though the final /Makefile may be omitted).
This script may be run from the toplevel directory (the one containing configure) or from one of it's subdirectories.
If the source directory is different from the build directory (see the environment variables below), it will be assumed that the
Makefile.am and Makefile.in belong beneath the source directory and that the Makefile belongs beneath the build directory.
This utility is part of the KDE Software Development Kit.
ENVIRONMENT
One of the following variables (but not both) should be set if the source directory is different from the build directory. If the build
directory is simply a subdirectory of the source directory, the simpler variable OBJ_SUBDIR should be used.
OBJ_SUBJDIR
Indicates that the build directory is in the given subdirectory of the source directory. For instance, if the source directory is
kdesdk and the build directory is kdesdk/obj-i386-linux, then OBJ_SUBDIR should be set to obj-i386-linux.
OBJ_REPLACEMENT
A sed expression that is used to transform the source directory into the build directory. For instance, if the source directory is
~/src/kdesdk and the build directory is ~/src/kdesdk-obj, then OBJ_REPLACEMENT should be set to s#kdesdk#kdesdk-obj#.
