As a makefile user I can say the same, give a try to cmake (but also no 
idea, never used it before).

On the other side.. build system has been always broken for one or two 
days and "in my opinion", always go to be broken.. different system, 
different user, different preferences..

So my point is that every build system have the good/bad thing, but in the 
end is just a dev/user preferences and always go to by that, if you try to
work with the four at the same time, soon or later become a pain.

I always used makefile for my project and never has been a problem, when I
start working with blender, first try scons but I become tired of always 
have problem.. so I go back with makefiles.

my question is: is it really need work with the four ?
can you work only with one (cmake, make, scons, whatever) and let the 
dev/users of each build system update it ?

Don't get me wrong, if the decision is remove the makefiles, I can move to 
cmake and live with that... it is just that I want to see a "good reason" 
for remove the makefiles.
