Hello Guix!

The following 3 patches are some minor improvements for Qt in Guix.  They
allow them to use GTK themes, which noticeably improve the look of things such
as the file picker on systems using a GTK theme.  Passing the configure flags
via the #:configure-flags argument for qtbase allows package rewriting, for
example, building a static version of it:

--8<---------------cut here---------------start------------->8---
(use-modules (gnu packages qt)
             (guix packages)
             (guix transformations)
             (guix utils))

;;; Adapted from static-package in (guix build-system gnu).
(define* (static-package-qt p #:key (strip-all? #t))
  "Return a statically-linked version of package P.  If STRIP-ALL? is true,
use `--strip-all' as the arguments to `strip'."
  (package (inherit p)
     (let ((a (default-keyword-arguments (package-arguments p)
                '(#:configure-flags '()
                  #:strip-flags '("--strip-debug")))))
       (substitute-keyword-arguments a
         ((#:configure-flags flags)
          `(cons* "--disable-shared" "-static" ,flags))
         ((#:strip-flags flags)
          (if strip-all?
    (replacement (and=> (package-replacement p) static-package-qt))))

(define qtbase-static (static-package-qt qtbase))

(packages->manifest (cons qtbase-static))
--8<---------------cut here---------------end--------------->8---

I realized that there had already been the same fix on staging.  I had
to spend some time to manually resolve "conflicts" (which were not
immediately apparent due to code having changed place on core-updates).
The conflict cherry-picked from core-updates which ended up fixing this
was 30759c4aadf279e470e8d7f94de332a31c1b9f42.

I rebased the commits that had been pushed to master on that and a few
related others, and pushed as d5c9cc6d9d979bfca5f035429bcf510a0a2285a3,
which contains extra comments.

Thank you!
