user/qt5: Bump to 5.12.6 LTS

This updates Qt 5 to the latest LTS release available.  Notable changes:

* The infamous clipboard bug (upstream QTBUG-65145; Gerrit 254187) is fixed!

* Qt Declarative's "V4 JIT" is disabled globally on pmmx.  It is no longer
  (easily) possible to turn off the JIT selectively based on CPU capability.

* Qt Script builds correctly on GCC 8 now.

This does not include:

* Build testing of Qt Multimedia (yet); this depends on the time64-isation
  of the alsa-lib package (at least).

* Build testing of Qt Speech (yet); speech-dispatcher also deps on alsa-lib
  indirectly.

* Qt WebKit 5.212.  This will be committed later.

+It is no longer possible to remove the SSE2 requirement.

+So we remove the JIT entirely on pmmx/x86.

-Subject: [PATCH v2] Do not make lack of SSE2 support on x86-32 fatal
-
-When an x86-32 CPU does not have SSE2 support (which is the case for
-all AMD CPUs, and older Intel CPUs), fallback to use the interpreter,
-otherwise use the JIT engine.
-
-Even then, make the lack of SSE2 support on x86-32 fatal when trying
-to instantiate a JIT engine, which does require it.
-
-Refactor the required CPU support check into a new pair of privately
-exported functions to avoid duplicating the logic, and do so in
-functions instead of class members to avoid changing the class
-signatures.
-
-Version: 5.7.x
-Bug-Debian: https://bugs.debian.org/792594
