Please support MSYS2 MINGW64

$ make
find: ‘/usr/share/fonts’: No such file or directory
Makefile:21: *** Liberation Mono Regular font not found: please install it or provide correct FONTSPATH.  Stop.

There is no /usr/share/fonts on MSYS2 MINGW64:

$ ls /usr/share/fonts
ls: cannot access '/usr/share/fonts': No such file or directory

[ec429]

Wherever fonts are stored on your system, pass that path into make with the FONTSPATH variable, i.e. make FONTSPATH=/path/to/fonts. The build system will then search within that path and its subdirectories for LiberationMono-Regular.ttf.
