`wasm-unknown-unknown` support?

[adenine-dev]

When building for wasm-unknown-unknown, I get the following error:

error: failed to run custom build command for `harfbuzz-sys v0.5.0`

Caused by:
  process didn't exit successfully: `/Users/adenine/Developer/grove/target/debug/build/harfbuzz-sys-a0780e23bb96e841/build-script-build` (exit status: 1)

Is this something that's possible?
