wasm: building example app fails to link

While updating and trying to fix a bug in wasm, I noticed my usual test app - textedit example did not link with this error:

I narrowed it down to this commit:

configure: actually resolve libraries into full filepaths

521a85395da1a2728902816c072ec46bcb0ad380

It would seem that the -s USE_FREETYPE=1-s USE_LIBPNG=1 -s USE_ZLIB=1

 are not getting passed on so the emscripten's libraries are not getting used.

When I explicitly add them to wasm-emscripten/qmake.conf  that horrible linking error is gone but symbols get defined multiple times.

error: Linking globals named 'png_sRGB_table': symbol multiply defined!
