I experienced the same last week. If you choose a current 5.13 branch of qtbase, it should work.
Also the latest qt5.git integration contains a build fix for this.
Hence, I’d recommend to switch to 5.13 and use latest emscripten SDK.

Subject: [Interest] WAS is failing to compile under Ubuntu
Hello, Qt devs,
A couple of devs, including me, tried to build and install Qt for WA under a recent Ubuntu.
We all followed the instructions from the blog post: https://blog.qt.io/blog/2018/11/19/getting-started-qt-webassembly/
However, for some reason the build fails at:
qsimd_p.h:196:14: fatal error: 'x86intrin.h' file not found
# include <x86intrin.h>
My em++ looks as follows:
$ em++ -v
emcc (Emscripten gcc/clang-like replacement + linker emulating GNU ld) 1.38.28
clang version 6.0.1 (emscripten 1.38.28 : 1.38.28)

How can we debug the problem? I've also tried to do following export CPLUS_INCLUDE_PATH=~/bin/emsdk/clang/tag-e1.38.28/build_tag-e1.38.28_64/lib/clang/6.0.1/include/ which results in the build failing due to missing symbols.
Thank you for your response
