Ok, I have repeated the steps from scratch both in mingw32_shell.bat and 
in mingw64_shell.bat shell. As source I have used emacs-master.tar.gz 
(commit 416dd4af, Dmitry Antipov 2014-09-09 11:43:22 (GMT)) from Git mirror.

1) mingw32_shell.bat (failure)

$ ./autogen.sh
$ ./configure
[...]
Configured for `x86_64-pc-mingw32'.
[...]

$ make
[...]
if test "no" = "yes"; then \
  rm -f bootstrap-emacs.exe; \
  ln temacs.exe bootstrap-emacs.exe; \
else \
  ./temacs --batch --load loadup bootstrap || exit 1; \
  test "X" = X ||  -zex emacs.exe; \
  mv -f emacs.exe bootstrap-emacs.exe; \
fi
/bin/sh: riga 4: ./temacs: cannot execute binary file: Exec format error
Makefile:828: set di istruzioni per l'obiettivo "bootstrap-emacs.exe" 
non riuscito
make[1]: *** [bootstrap-emacs.exe] Errore 1
make[1]: uscita dalla directory "/tmp/emacs-master/src"
Makefile:379: set di istruzioni per l'obiettivo "src" non riuscito
make: *** [src] Errore 2

2) mingw64_shell.bat (success)
$ ./autogen.sh
$ ./configure --without-imagemagick
$ make

completed successfully! Maybe the failure I saw before was a consequence 
of the '-j3' option..

So, which way (x86_64-w64-mingw32 / x86_64-pc-mingw32) is the best to 
build Emacs on MSYS2?

Ciao,
 Angelo.
