Only the cc-wrapper supports this right now, but these may be reused by
other wrappers, builders or setup hooks.
cc-wrapper supports the following flags:
* fortify
* stackprotector
* pie (disabled by default)
* pic
* strictoverflow
* format
* relro
* bindnow
This is so that the Unison wrapper can be generated with
makeWrapper.
* Use makeWrapper as a buildInput everywhere.
* Updated BitTorrent, cvs2svn.
