Output of emerge --info

I added WebAssembly to LLVM_TARGETS and rebuilt with --changed-use.

When I try to compile a test program with "clang --target=wasm32 ..." I get the following error:

clang-11: error: unable to execute command: Executable "wasm-ld" doesn't exist!

I searched for "wasm-ld" and could not find it anywhere.

I had to compile sys-devel/clang with default-lld

just installing sys-devel/lld should be enough, it's packaged separately. it will provide wasm-ld. regardless of flags on clang.
