1. Object files, libraries, and compiled executables are put into subdirectories. 2. The shared library is linked from individual object files. This provides for greater parallelism on large desktops while at the same time making for easier builds on small (i.e. embedded) systems. Fixes issue #279. 3. One program, db_bench, is compiled using the shared library. 4. The source file for "leveldbutil" was renamed from leveldb_main.cc to leveldbutil.cc. This provides for simpler makefile rules. 5. Because all targets placed the library (libleveldb.a) at the top level, the last platform built (desktop/device) always overwrote any prior artifact. ------------- Created by MOE: https://github.com/google/moe MOE_MIGRATED_REVID=113407013
