[QtonPi] Bakeqtpi for osx updated

[Trismer Technologies]

Hi,

   I have updated our modified Bakeqtpi script for osx at:
https://gitorious.org/~trismer/bakeqtpi/trismer-bakeqtpi-osx

It includes many changes already done by Kieran Evans and some our 
modifications for Mac OSX. Feel free to try it. Our tests confirmed that it 
performs the whole process of building Qt5 for RPi. It also fixes problems 
with:

cross-compile-tools and symbolic links
wrong armv6 vfp detection in javascript backend


Best regards,
