Reuses the cc.Stripper logic. Abstracts Stripper to avoid the spreading of references to the cc package. rustc requires unstripped libraries (precisely, with the `.rustc` section) when building dependent targets. Contrary to cc, the output of a compiler module will remain unstripped and only an extra build rule will be added. This rule will be referenced at install time (in baseCompiler.install or androidmk). This change drastically reduces the size of the installed libraries: (unstripped, from out/target/product/crosshatch/system) $ find . -name \*.dylib.so -print0 | du -c --files0-from=- 149996 total (stripped, with this change) $ find . -name \*.dylib.so -print0 | du -c --files0-from=- 42380 total Bug: 153430439 Test: cd external/rust; mma Change-Id: I94fd8bbcec97e0610aa325d3db4460be84d01734
