With wxWidgets 2.9.2 now in Externals, SCons was the only external dependency other than Xcode and building just SCons from Macports caused a fair mount of extra stuff to be built unnecessarily, so just include a copy of scons-local. Always build wxWidgets from Externals which allows us to get rid of the home-grown autoconf machinery in SconsTests. The main use case for args.cache was the wxconfig option, which is no longer relevant after the above changes and caching options has a lot of potential for confusion, especially since other build systems don't tend to do this, so we no longer do it now. git-svn-id: https://dolphin-emu.googlecode.com/svn/trunk@7381 8ced0084-cf51-0410-be5f-012b33b47a6e
