- missing register definitions from asm/ptrace.h
- non-POSIX-compliant ucontext_t on PPC32 with glibc

Addresses CVE-2015-3239: Off-by-one error in the dwarf_to_unw_regnum
function in include/dwarf_i.h in libunwind 1.1 allows local users to
have unspecified impact via invalid dwarf opcodes.
Upstream stable-v1.2 fixed the missing unwind_i.h issue but no new
tarball is released yet

The package Makefile was based on work at link [1] with the following
changes
1. Disable minidebuginfo support thus no dependency on liblzma
2. Add 2 patches for building against musl-libc and building with
mips16 enabled
3. Add LICENSE and DEPENDS info, etc.
