I did a rebuild overnight to make sure everything is still working and
kept a log. Unfortunately, no magical insights from it though.

However, it looks like the c++14 thing was a red herring - I see plenty
of references to it (including checking for its capability).

I noticed that ninja itself (version, whatever) is probably not
implicated; the configuration finds the system ninja to be too old and
doesn't use it:

Checking for system ninja...
Found ninja from path: /usr/bin/ninja
+ /usr/bin/ninja --version
> 1.10.0
Ninja version too old
Building own ninja

I also found the area where OP's build failed. No failure here but it is
interesting that the progress indicator was quite different. In my build
it was [15020/16427] but for OP it was [641/2162]. I wonder if that
means different things are being built - leading to question of what the
configuration discovered on the build machine (therefore determining
what needed to be built).

My build was on a clean, up to date, VM - nothing else installed except
the required ninja, python3, meson & libxkbcommon packages.

A question for Wedin: did you have those packages installed before
starting build of qt5? Also, any other packages installed that may have
influenced qt5's build configuration (some are listed in the qt5.README
file)?
