Get rid of a number of unnecessary env.Clones. Use SCons' convenient # shorthand for the root of our tree. Also various minor cleanup of SConscripts. git-svn-id: https://dolphin-emu.googlecode.com/svn/trunk@5915 8ced0084-cf51-0410-be5f-012b33b47a6e

Build GLEW, SDL and zlib as static libraries from Externals as with LZO/SFML/SOIL and subject to the same shared_foo exception options. This makes building a self-contained distribution package much easier. TBD: Cg and wxWidgets 2.9. git-svn-id: https://dolphin-emu.googlecode.com/svn/trunk@5712 8ced0084-cf51-0410-be5f-012b33b47a6e

Import('env')
In the SCons build, skip the generation of static libraries and just operate on lists of object files instead. This helps with LTO since LLVM/clang LTO is completely broken by static libraries. It also helps identify symbol clashes between components like the former plugins. Many linkers also expect static libraries to form a strict DAG which turns out be a difficult rule to uphold in practice, especially since some of our platforms aren't picky about this. LTO builds currently appears to crash at runtime because of the static wx libs. git-svn-id: https://dolphin-emu.googlecode.com/svn/trunk@7056 8ced0084-cf51-0410-be5f-012b33b47a6e

Build with -msse3 on OS X. The first Intel Macs were Core Duo/Solo, which had SSE3. Keep -msse2 on other platforms. Not sure if there are actually any Dolphin-capable machines out there without SSE3, but.. Use -search_paths_first to give our statically linked libraries precedence over /usr/local/lib. Some work-in-progress changes to facilitate a more easily redistributable application bundle on OS X. Group compiler/preprocessor/linker flags together to make the full set more intuitively apparent. The various libraries in Externals have rather inconsistent conventions for include paths. Best to encapsulate that knowledge in foo/SConscript. Re-use utils.GenerateRevFile for all three places in the build system where we need the SVN revision number. git-svn-id: https://dolphin-emu.googlecode.com/svn/trunk@6030 8ced0084-cf51-0410-be5f-012b33b47a6e
