OSX: Use the oldest SDK, but always set our target to 10.8 

Build binaries usable on older machines even if older SDKs are not
installed. Older SDKs can no longer be installed on newer Xcode
versions.

# You can no longer install older SDKs in newer xcode versions, so it appears
# to be expected to use the newer SDKs, but set command line flags in order to
# target older Mac OS X versions.

# We'll use the oldest SDK we can find, and then use the -mmacosx-version-min
# and MACOSX_DEPLOYMENT_TARGET flags to set our minimum version.
