Require OSX 10.6, 64-bit

Drop support for 32-bit or pre-10.6 Macs.

Also, some of the OSX build docs hadn't been updated since the
autotools change.

+If you are building `bitcoind` or `Bitcoin-Qt` for others, your build machine should be set up
 as follows for maximum compatibility:
 
 All dependencies should be compiled with these flags:
 
-    -mmacosx-version-min=10.5 -arch i386 -isysroot /Developer/SDKs/MacOSX10.5.sdk
+ -mmacosx-version-min=10.6
+ -arch x86_64
+ -isysroot $(xcode-select --print-path)/Platforms/MacOSX.platform/Developer/SDKs/MacOSX10.6.sdk
 
 For MacPorts, that means editing your macports.conf and setting
 `macosx_deployment_target` and `build_arch`:
 
-    macosx_deployment_target=10.5
-    build_arch=i386
+    macosx_deployment_target=10.6
+    build_arch=x86_64
 
 ... and then uninstalling and re-installing, or simply rebuilding, all ports.
 
 As of December 2012, the `boost` port does not obey `macosx_deployment_target`.
 Download `http://gavinandresen-bitcoin.s3.amazonaws.com/boost_macports_fix.zip`

-`macosx_deployment_target`, but not both at the same time. For example, building
