Subject: [PATCH] configure: Recognize uname "Windows_NT" as using an .exe
 suffix

Busybox-w32 [1] works for building ffmpeg on Windows (as an
alternative to msys2, cygwin or WSL).

On busybox-w32, "uname" returns "Windows_NT"; recognize this
in exesuf() as having an .exe suffix.

If building in this environment with a mingw toolchain, one has
to explicitly set --target-os=mingw32. (We probably don't
want to imply that this uname, set as target_os_default, would
default to mingw?) But despite what is set with --target-os,
one can't override the configure variable "host_os", which
exesuf() has to recognize.
