min sized -lib (.a)

[bltpanda]

I followed the instructions to compile the library, creating a static library(.a) that contains only the simplest method. The final size is 221kb. Is this in line with expectations?

[package]
name = "greetings"
version = "0.1.1"
authors = ["fluffyemily <fluffyemily@mozilla.com>"]
description = "Example static library project built for iOS"
publish = false

[target.'cfg(target_os="android")'.dependencies]
jni = { version = "0.5", default-features = false }

[lib]
name = "greetings"
crate-type = ["staticlib", "cdylib"]

[profile.release]
debug = false
opt-level = "z"     # Optimize for size.
lto = true          # Enable Link Time Optimization
codegen-units = 1   # Reduce number of codegen units to increase optimizations.
panic = "abort"     # Abort on panic
strip = true        # Automatically strip symbols from the binary.
