Stephan Bergmann 811769f009 Consistently use __EMSCRIPTEN__ instead of EMSCRIPTEN macro 
...as emsdk 5.0.3 deprecated the predefined EMSCRIPTEN macro (see
<https://github.com/emscripten-core/emscripten/commit/506052bd8b4e23ded7f2351c62ca3b24d40c8cf3>
"Warn about usage of deprecated EMSCRIPTEN macro. NFC (#26381)"), causing
failures like

To avoid confusion, also suppress the -D$(OS) in
solenv/gbuild/platform/unxgcc.mk that would unnecessarily keep defining
EMSCRIPTEN.
