    Makefile: Fix build on MSYS2 and Cygwin
    
    The host compiler on MSYS2 and Cygwin does not allow the -fPIC option,
    issuing a warning that is treated as an error and stops the build.
    Detect whether we're running under MSYS2 or Cygwin and avoid adding
    -fPIC to prevent the error from happening.
    
    Tested on Linux, MSYS2 and Cygwin.

    [dwg: Added explicit empty CFLAGS for clarity]
