[bug#62916] [PATCH v2 1/1] gnu: p11-kit: fix build on mingw.

[Vivien Kraus via Guix-patches via <guix-patches@gnu.org>]

* gnu/packages/patches/p11-kit-fix-build-system-for-mingw.patch: New patch. It
makes sure that all symbols are defined when linking objects.
* gnu/packages/tls.scm (p11-kit) [on target-mingw?] [phase
'apply-mingw-patch]: New phase, similar to what’s done with hurd.
* gnu/packages/tls.scm (p11-kit) [native-inputs]: also add the autotools on mingw.
