Not sure what the errors mean
The errors are to take quite literally:

You execute "make" with the arguments "foo" "." "make" and "$(EXE)".

The first error is from the shell, because "$(EXE)" means run command "EXE" in a subshell and put its output here. The shell thinks that the rest of the command depends on what EXE might output and therefor execute it first - as there is no "EXE, this fails.

Next, "make" is executed and takes the argument: "foo". For "foo" exists a target to make and "make" does try to make it but notices that it has already done so and in the meantime "foo" hasn't changed - so it tells you that "foo" is already up to date. Next make tries to "make .". As "." is the current directory and there is no rule in your makefile describing how to make "." "make" tells you so. Finally it tries to make "make", which would be (like ".") a perfectly valid target to make - IF it would exist in your makefile. As it doesn't, "make" tells you the same as with ".": it can't make it, because you haven't told it how.

But instead of writing a long-winded make-exegesis, i could probably tell you what you need to know, so: what exactly do you want to achieve? Have you ever used a makefile and know its purposes? Its syntax?

I hope this helps.

xmkmf

XMKMF(1)						      General Commands Manual							  XMKMF(1)

NAME

       xmkmf - create a Makefile from an Imakefile

SYNOPSIS

       xmkmf [ -a ] [ topdir [ curdir ] ]

DESCRIPTION

       The xmkmf command is the normal way to create a Makefile from an Imakefile shipped with third-party software.

       When  invoked with no arguments in a directory containing an Imakefile, the imake program is run with arguments appropriate for your system
       (configured into xmkmf when X was built) and generates a Makefile.

       When invoked with the -a option, xmkmf builds the Makefile in the current directory, and then automatically executes ``make Makefiles'' (in
       case  there are subdirectories), ``make includes'', and ``make depend'' for you.  This is the normal way to configure software that is out-
       side the X Consortium build tree.

       If working inside the X Consortium build tree (unlikely unless you are an X developer, and even then this option is never really used), the
       topdir  argument  should be specified as the relative pathname from the current directory to the top of the build tree.	Optionally, curdir
       may be specified as a relative pathname from the top of the build tree to the current directory.  It is necessary to supply curdir  if  the
       current	directory  has	subdirectories, or the Makefile will not be able to build the subdirectories.  If a topdir is given, xmkmf assumes
       nothing is installed on your system and looks for files in the build tree instead of using the installed versions.
