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]
