Unable to build openssl 0.7.8 for ARM

Hi,

I am trying to build the latest version of crate openssl (aka 0.7.8) for Raspberry Pi 2 (ARMv7) through a Yocto/OE recipes that depends on meta-rust but it fails due to the following issue:

| /leon/GDP/genivi-demo-platform-rpi/gdp-src-build/tmp/work/cortexa7hf-vfp-vfpv4-neon-poky-linux-gnueabi/rvi-sota-client/git-r0/cargo_home/registry/src/github.com-88ac128001ac3a9a/openssl-0.7.8/src/ssl/mod.rs:830:50: 830:58 error: mismatched types:
|  expected `*const i8`,
|     found `*const u8`

I noticed that similar bug has been already reported as #314. The solution seems simple. I will try to send a Git pull request for a review asap.

Best regards, Leon
