Building with cargo --target wasm32-wasi produces very small wasm/wat file

[tpmccallum]

Hi
If I clone and build wasm-flate using the following command and convert to wat

cargo build --target wasm32-wasi --release --features "strings"

./wasm2wat ~/wasm-flate/target/wasm32-wasi/release/wasm_flate.wasm  -o ~/wasm_flate.wat

The wat file is only about 9 lines long (as shown below).

(module
  (table (;0;) 1 1 funcref)
  (memory (;0;) 16)
  (global (;0;) (mut i32) (i32.const 1048576))
  (global (;1;) i32 (i32.const 1048576))
  (global (;2;) i32 (i32.const 1048576))
  (export "memory" (memory 0))
  (export "__data_end" (global 1))
  (export "__heap_base" (global 2)))

There did not seem to be any errors when compiling as shown below.
