Merge a bunch of SConscript.main back into SConscript.main.linux. My goal is to track .main as close as possible to minimize divergence.
Using this (and the split SConstruct that keunwoo already wrote) you can build third_party by: scons Hammer/third_party and you can attempt to build base, though there's still a lot of work to be done. git-svn-id: http://src.chromium.org/svn/trunk/src/build@265 4ff67af0-8c30-449e-8e8b-ad334ec8d88c
