wrong build dir path being called for wasm apps

When I try to build a webassembly example app on Linux or Windows, using webassembly binary release, I get this error:

em++: error: /home/qt/work/qt/qtbase/build/target/plugins/platforms/libqwasm.a: No such file or directory ("/home/qt/work/qt/qtbase/build/target/plugins/platforms/libqwasm.a" was expected to be an input file, based on the commandline arguments provided)

On mac, it seems to work.

It seems to be  build machine path.
