EDIT: I'll bump dependencies again to see how much it helps when I get some time.
EDIT2: Linked upstream issue for PowerPC64LE

[mati865]

Rebased with newer versions.
Android 64bit should get as far as 32bit now, it still needs fixing in libc or xattr crates.
PowerPC64LE and NetBSD will most likely fail again.

[Stebalien]

xattr v0.2.2 should fix builds on unsupported platforms

[mati865]

@Stebalien thank you for fix and notification.

PR rebased with updated xattr and other minor bumps, PowerPC64LE issue will be fixed in Rust 1.28.
Updating hyper to 0.12 could workaround the issue but it would be breaking change.
