I can't completely follow the twisty maze of Makefiles and included .mk
files, but the root cause seems to be that www/firefox depends on
several wasi ports, namely devel/wasi-libcxx, devel/wasi-libc, and in
particular devel/wasi-compiler-rt13:

BUILD_DEPENDS+= ${LOCALBASE}/share/wasi-sysroot/lib/wasm32-wasi/libc++abi.a:devel/wasi-libcxx \
                ${LOCALBASE}/share/wasi-sysroot/lib/wasm32-wasi/libc.a:devel/wasi-libc \
                ${LOCALBASE}/llvm${LLVM_DEFAULT}/lib/clang/${LLVM_VERSION}/lib/wasi/libclang_rt.builtins-wasm32.a:devel/wasi-compiler-rt${LLVM_DEFAULT}

The problem is that there *is* no devel/wasi-compiler-rt15 port,
although I heard rumours of it being worked on. But apparently it has
not yet materialized, and neither has corresponding port for llvm16 or
17. It's a pity these can't be included in the regular llvm ports.

As to how the Makefile maze magically changes LLVM_DEFAULT and
LLVM_VERSION, I have no clue, and I don't want to debug the whole ball
of mud. :)
