Composition recipe that wraps pantry's existing builds:
- llvm.org → clang + clang++ + lld + LLVM binutils
- mingw-w64.org → Windows runtime (headers + CRT + winpthreads),
built from source — see companion pantry#13047
The build script just generates per-target POSIX-sh driver wrappers
shimming clang with `--target=<target> --sysroot=<mingw-w64.org>`,
plus binutils-equivalent aliases (ar/ranlib/strip/nm/objdump/objcopy/
windres/dlltool/ld) for autotools and Makefile compat.
End-to-end test: cross-build hello.c for x86_64 + aarch64 Windows
targets, PE/COFF magic-byte check, optional wine runtime test.
From-source over vendored (no `warnings: vendored`) per pantry policy
and the project goal of source-buildable independence.

Summary
llvm.org/mingw-w64as a composition recipe: wraps pantry'sllvm.org(clang + lld + LLVM tools) withmingw-w64.org(Windows runtime — headers + CRT + winpthreads) to produce a self-contained, from-source Windows cross-compiler toolchain.--target=<target> --sysroot=<mingw-w64.org>, plus binutils-equivalent aliases (ar / ranlib / strip / nm / objdump / objcopy / windres / dlltool / ld) for autotools + Makefile compat. All real compilation happens in the two component recipes.warnings: vendored. Replaces the prior vendored approach (new(llvm.org/mingw-w64): LLVM-based mingw-w64 cross-compiler (Windows-target toolchain) #12984, which pulled mstorsjo/llvm-mingw prebuilt tarballs). Companion to new(mingw-w64.org): Windows runtime libs (headers + CRT + winpthreads) — from source #13047 (mingw-w64.orgruntime).Test plan

This supersedes #12984 — that branch pinned the vendored-tarball approach. Per the project goal of source-buildable independence ("être capable de compiler depuis les sources est un gage d'indépendance"), this PR drops the vendored path entirely and composes pantry's own builds.
Closes #12984 (will close once this is reviewed-OK).
