There's ultimately no difference as doing "make" followed by "make install" is 
equivalent to just doing "make install". Make files contain various targets, 
each of which has not only a sequence of build commands, but also a set of 
other targets it depends on having already been built. The default make target 
is "all", so "make" is the same as "make all". The "install" target is 
dependent on the "all" target. This dependency ensures that the "all" target 
will be built before the "install" target is built.

Now, because I hate lying, I better tell the whole truth. The default target is 
only "all" because, by convention, make file writers ensure that it is. The 
real default make target is the first target that gets defined. So, good make 
file writers ensure that "all" is the first defined target, and that "install" 
depends on "all".
