Subject: [PATCH] GHA: main.yml/main-aarch64.yml: WASM build

-DEMSCRIPTEN=1 appears to not be present any more by default in emcc compiler.

There is -D__EMSCRIPTEN__=1 but that would require modifying many locations
in the codebase which are already being reviewed separately under a single
source multi-platform build cleanup process.

Anyhow maybe ./configure would set -DEMSCRIPTEN=1 itself, much like -Dlinux=1
for other targets.  This commits defers evaluation on that until later and just
restores how it worked before.
