There are a lot of people who use makefiles for C projects, but most of those people don't write them by hand.
They use a frontend that generates a vastly complex and arcane makefile using either automake, cmake, qmake, etc.
These makefiles are utterly unmaintainable and deserve a place next to 'goto' in the section labeled 'considered harmful'... but they serve a purpose; correctly collecting build settings, templates and metadata and using those to construct the correct makefile.
That doesn't count as 'using make'.
There are a vanishingly few projects that actually use make; google for it's NDK builds (and a few other things; but these are massive recursive makefile monsters that you have a tiny safe api to work with), LUA with its 15 makefiles, one for each platform. There are a couple of other examples, but not many. I can't think of any big ones off the top of my head.
I think we can safely say that writing a Makefile to build your C code is a bad idea.
