Compile tesseract for iOS SDK 6.0

Update 10/25/12

Added instructions to integrate an armv7s slice in liblept.a and libtesseract_all.a.

Update 09/24/12

To make the iOS integration easier, I made a Github repo containing an Objective-C wrapper for Tesseract. It relies on an other repo containing tesseract & leptonica libs. Feel free to improve them !

More informations about these repos on my next article.

Here is why: Xcode 4.5 and iOS SDK 6.0 don’t support armv6 anymore.

So here are the steps to build tesseract-ocr for iOS SDK 6.0.
