Build fails for wasm32-wasi target: _Float16 is not supported on this target

Hello. As you may know, Mozilla bundles an older version of simde with their sources, and it works. I'm trying to use the latest version (0.8.2) installed by the FreeBSD port on my machine.

Unfortunately, compiling for the wasm32-wasi fails:

clang++18 --target=wasm32-wasi --sysroot=/opt/share/wasi-sysroot -o sse_optimized.wasm -c -I/n/home/ports/www/firefox/work/firefox-126.0.2/media/libsoundtouch/src -I/n/home/ports/www/firefox/work/.build/media/libsoundtouch/src -I/n/home/ports/www/firefox/work/.build/security/rlbox -I/n/home/ports/www/firefox/work/.build/dist/include -I/opt/include/nspr -I/opt/include -I/opt/include/nss -I/opt/include/nspr -I/n/home/ports/www/firefox/work/.build/dist/include/nss -I/opt/include -I/opt/include/libpng16 -I/opt/include/pixman-1 -Os -fno-exceptions -fno-strict-aliasing -DNDEBUG=1 -DTRIMMED=1 -DMOZ_IN_WASM_SANDBOX -DMOZ_SAMPLE_TYPE_FLOAT32=1 -DSOUNDTOUCH_ALLOW_SSE=1 -DSOUNDTOUCH_WASM_SIMD=1 -DSIMDE_ENABLE_NATIVE_ALIASES=1 -DBUILDING_SOUNDTOUCH=1 -DST_NO_EXCEPTION_HANDLING=1 -msimd128 -I/n/home/ports/www/firefox/work/.build/dist/stl_wrappers -MD -MP -MF .deps/sse_optimized.wasm.pp   /n/home/ports/www/firefox/work/firefox-126.0.2/media/libsoundtouch/src/sse_optimized.cpp

Is this a bug? Perhaps, I can set the SIMDE_FLOAT16_API to something as a work-around?
