Includes fixes for out dirs at absolute paths, and symlinks to absolute paths. Also squashes support for exporting make vars, which previously happened in a later patch (which got moved first, since it's mostly infrastructure changes). Original message: cc_prebuilt_binary doesn't work well for host tools because they'll often be using their own versions of shared libraries that may not be compatible with what we build. So add a module type that allows genrules to use one of these prebuilts as a tool. Like other prebuilts, we'll use the source module if we have it, or the prebuilt otherwise. It supports adding extra dependencies for shared libraries or other data files that are necessary to run the tool. Any genrules using the tool will be rerun if any of the dependencies change. Bug: 128690776 Test: treehugger Test: build one-true-awk using genrule with bison Test: with OUT_DIR=$PWD/out Test: with OUT_DIR pointing to an absolute symlink Change-Id: I662296cb55503b6a10ec5e5465b138e9edeb71f3
