build: fix arm build after v8 upgrade

V8 was upgraded to 3.18 in commit 9f68226. The knobs that control the
ARM build have changed in a number of ways. This commit patches the
configure script to reflect that. Should fix the Raspberry Pi build.

Fixes #5329.

Switch to always use args.This() to retrieve object instance.

Allow the IPv4-mapped-as-IPv6 style address.

Merge branch 'v0.11.1-release'

path: add path.isAbsolute(path)

An absolute path will always open the same location regardless of your
current working directory. For posix, this just means path.charAt(0) ===
'/', but on Windows it's a little more complicated.

Fixes joyent/node#5299.
