Rename make folder to get rid of build error. (#12880)

When trying to build firmware with current directory in PATH environment
it scans for make command and generates "Permission denied" error in
case if current directory in PATH precedes /usr/bin/ directory.In my
case it was caused by incorrect pyenv init script.

Rename make folder to avoid errors like this.
