Failed to compile 0.28

[boorbajones]

with make that worked fine, I then tried

Job: make release_lnx
make release_lnx
cargo build --release --target=x86_64-unknown-linux-musl

I tried first with rust 1.6.5, then with rust 1.6.9, but that did not solve the matter.

x86_64-unknown-linux-musl is a special target to avoid the dependency to glibc.
It requires target installation through rustup target add x86_64-unknown-linux-musl.

If you doesn't use it, cargo build --release can be used.
