1.38.46-upstream regression on sdl2 build

[pmp-p]

just tested the new tag with : ./emsdk install --embedded 1.38.46-upstream
embuilder.py build --pic sdl2 gives strange messages now:

embuilder.py build --pic sdl2
embuilder:INFO: building and verifying sdl2
cache:INFO: generating port: libSDL2.a... (this will be cached in "/opt/sdk/emsdk-upstream/.emscripten_cache/wasm-obj-pic/libSDL2.a" for subsequent builds)
