[Development] Standard options & deploying on Mac OS X 10.6 while building on 10.7

[Vincent]

OK, now I'm trying to build Qt against 10.6 sdk on the 10.7 machine. I've
copied from XCode 4.3.3 the macosx10.6 sdk along 10.7 & 10.8 SDK's.

Then configuring with:
 ./configure -prefix $PWD/qtbase -opensource -debug-and-release -nomake
examples -nomake demos -no-c++11 -sdk macosx10.6 -v

It seems to accept the value of the argument -sdk (if I provide a wrong
value, a warning is raised).

However, when looking at the clang++ option run during configure step, it
seems MacOSX10.8 sdk is used (see -isysroot argument):

/Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin/clang++
-c -o qcore_mac.o -pipe -isysroot
/Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX10.8.sdk

and the configure step ends up with an error (here 10.6 sdk seems at work):
