Re: Build LO for Android on Mac OS 10.8

In my environment, Mac OS 10.8 and Xcode 4.4.1, without specifying Mac OS
X SDK version, it picks 10.6 as Mac OS X SDK.
And then it failed since it can't find gcc-4.2. So I tried to use option
--with-macosx-sdk with 10.8.
It's building now!

During applying --with-macosx-sdk option, I found some typos (maybe?), one
of them leads me to apply wrong option'--with-macox-sdk'.

I list them below just in case you are interested:

And I also pass the --with-macosx-sdk option through to the "BUILD
platform configuration" to make it work:

Not sure I'm doing it in a appropriate approach though (This is my first
time to get involved with auto-config/autogen stuff).
