Support for non-greedy mode.
Previously when we encountered a target declaration, we would always
recursively load the deps and write the build file for that target. This is
"greedy mode."
This patch adds a non-greedy mode where a "should generate" but is pushed
recursively through the dependency tree. In this mode, targets without the bit
set will not have their dependencies loaded, and will not have buildfiles
written to disk.
The current implementation sets greedy mode for the default toolchain, and
non-greed mode for alternate toolchains. The reasoning is that because a
target depends on something in another toolchain, we don't want to do an
entire build in that alternate toolchain, but just do the minimum dependencies
in that alternate toolchain.
