    Description

      Configuring with

      ./configure -xplatform wasm-emscripten -nomake examples -skip qtwebengine -prefix $PWD/qtbase

      fails with 

      > em++ -s WASM=1 -s FULL_ES2=1 -s ALLOW_MEMORY_GROWTH=1 -s USE_WEBGL2=1 -s NO_EXIT_RUNTIME=0 -s ERROR_ON_UNDEFINED_SYMBOLS=1 --bind -s "BINARYEN_METHOD='native-wasm'" -s "BINARYEN_TRAP_MODE='clamp'" -O3 -o ./verifyspec.js verifyspec.o

      with emcc version 1.38.25.

      BINARYEN_METHOD is set in qt-everywhere-src-5.12.1/qtbase/mkspecs/wasm-emscripten/qmake.conf and removing the particular line fixed the issue, but I am not sure if that is the correct way to fix it.
