There is definitely a scripted way to do this.
i use this small makefile (see in the attachment) instead of the
automake generated one.
This makefile builds make from all .c files located in src/ and lib/.
Keep your src/ and lib/ free of stray .c files.
This makefile also correctly handles removals of header files and all
other known .d file necessities.

To use it
1. Create a subdirectory in your make source code directory. Step to
this newly created subdirectory.
2. Run ../configure. This needs to be done once to generate config.h.
3. Run make -f ../test.mk.
4. Checkout another commit and run make -f ../test.mk. No need to run
configure or bootstrap again.

Here is a sample bash session.

This makefile assumes the gcc depfiles format. See here
https://github.com/dgoncharov/efficient-autodeps-with-gmake how to
modify this makefile if your compiler generates  depfiles of the other
format.
