Round 2! Now for some patches applied to mingw-w64 itself, rather than just binutils.

I've checked:
- That the mode of the patches are correct
- guix build mingw-w64-{x86_64,i686}{,-winpthreads}
- guix build hello

-----

These patches were originally found at the debian mingw-w64 team's
mingw-w64 repo, and should improve the reproducibility of our mingw-w64
toolchain.

* gnu/packages/patches/mingw-w64-dlltool-temp-prefix.patch: New file.
* gnu/packages/patches/mingw-w64-reproducible-gendef.patch: New file.
* gnu/local.mk (dist_patch_DATA): Update accordingly.
* gnu/packages/mingw.scm (make-mingw-w64): Apply patches.

Hello Carl,

This patch LGTM. Do you know if there are plans to apply those patches
mainline?

Thanks,

Mathieu

Also you can add a break after "patches" so that you respect the 78
columns limit, this way:

--8<---------------cut here---------------start------------->8---
    (patches
     (search-patches "mingw-w64-6.0.0-gcc.patch"
                     "mingw-w64-dlltool-temp-prefix.patch"
                     "mingw-w64-reproducible-gendef.patch"))))
--8<---------------cut here---------------end--------------->8---

Thanks,

Mathieu

Great to hear Mathieu, I will push my changes along with the line break suggestion.

Not sure about plans to apply patches mainline… I will reach out to the original author to ask about this.

Cheers,
Carl Dong
