If someone tells what does the Cygwin Make print under --version, and
if there's something Cygwin-specific there, then yes, we could test
that in nt/configure.bat.

Failing that, w32proc.c:w32_executable_type has code to detect Cygwin
executables by scanning their DLL import table for cygwin.dll.  We
could start the build by compiling a simple program to diagnose
make.exe using that method.  Seems a bit gross, though.
