For sanity check I removed the tree and repeated the steps:

$ aunpack emacs-bfbdf4eb892935536fc665d6cc986fd669364263.tar.gz
$ cd emacs-bfbdf4eb892935536fc665d6cc986fd669364263/
$ patch nt/mingw-cfg.site ../android-01.patch
$ patch nt/mingw-cfg.site ../android-02.patch
$ patch nt/mingw-cfg.site ../android-03.patch

$ tail /tmp/emacs-bfbdf4eb892935536fc665d6cc986fd669364263/nt/mingw-cfg.site

# Don't build the Gnulib nanosleep module: it requires W2K or later,
# and MinGW does have nanosleep.
gl_cv_func_nanosleep=yes
# Suppress configure-time diagnostic from unnecessary libxattr check,
# as xattr will not be supported here.
enable_xattr=no
# Don't build gnulib printf either.
ac_cv_func_vasprintf=yes
gl_cv_func_vasprintf_posix=yes


$ ./autogen.sh
$ ./configure
