Change Description

Per discussion with @richard on IRC today, we're going to try to get the linux-arm patches merged piece by piece rather than having me rebase the whole thing constantly. This MR covers the openssl project and its dependencies. The resulting openssl executable works on my Asus C201 (modulo a missing libssp shared library, which is distributed outside of the openssl project). I haven't tested targets other than linux-arm, but I would be mildly surprised if this MR breaks anything for x86 targets.

(First time sending an MR since the MR template was added, let me know if I'm screwing anything up.)
