Avoiding installation

[John Kodis]

I'd like a program to be built when I type "make", but not have it
installed when I type "make install".  Is there a provision for this?

The motivation for this seemingly odd request is that I have a source
file that is normally used to generate an object file that is linked
into several other programs.  When this source file is compiled with
"$(CC) -o $@ -DMAIN $<" will build a stand-alone test program.  This
test program is what I'd like built but not installed.
