Does WebAssembly build set `OS_NAME` to `"Linux`" and architecture to one of x86, x86-64, ARM and ARM64? See `config-ix.cmake`, specifically this line `if (CRT_SUPPORTED_ARCH AND OS_NAME MATCHES "Linux")` should ensure that this is only built on Linux and `set(ALL_CRT_SUPPORTED_ARCH ${X86} ${X86_64} ${ARM32} ${ARM64})` should ensure that it's only built for x86, x86-64, ARM and ARM64.
