Differences from OE version:
* Add source checksums
* Correct LICENCE and move to .inc file
* Update HOMEPAGE
* Don't specify DEFAULT_PREFERENCE
* Remove S and SRC_URI from 4.7.1 (duplicates of .inc file values)
* Use http source URL to match other Qt4 recipes
* Don't add back tools previously disabled in poky
Differences from current (plus the above):
* Add Qt 4.7.1 recipe
* Specify -embedded to remove dependency on X (as we are only building tools)
* Disable some other options to reduce dependencies
* Specify -no-freetype / -no-fontconfig in .inc file rather than in .bb
* Use INC_PR
* Whitespace fixes
