[PATCH v2 00/12] Upstream some more Git for Windows' patches

When rebasing a Git for Windows commit to enable Rust in Windows CI, I
noticed just how many of the preceding commits touching adjacent code
haven't been upstreamed yet. This patch series rectifies that.

Changes since v1:

 * Fixed the meson-side handling of the MINGW_PREFIX constant (this was not
   noticed in the Git for Windows project because it does not use Meson to
   build the project).

Johannes Schindelin (12):
  mingw: include the Python parts in the build
  mingw: stop hard-coding `CC = gcc`
  mingw: drop the -D_USE_32BIT_TIME_T option
  mingw: only use -Wl,--large-address-aware for 32-bit builds
  mingw: avoid over-specifying `--pic-executable`
  mingw: set the prefix and HOST_CPU as per MSYS2's settings
  mingw: only enable the MSYS2-specific stuff when compiling in MSYS2
  mingw: rely on MSYS2's metadata instead of hard-coding it
  windows: skip linking `git-<command>` for built-ins
  mingw: always define `ETC_*` for MSYS2 environments
  mingw: ensure valid CTYPE
  mingw: allow `git.exe` to be used instead of the "Git wrapper"
