Add a Go replacement for our top-level Make wrapper Right now this mostly just copies what Make is doing in build/core/ninja.mk and build/core/soong.mk. The only major feature it adds is a rotating log file with some verbose logging. There is one major functional difference -- you cannot override random Make variables during the Make phase anymore. The environment variable is set, and if Make uses ?= or the equivalent, it can still use those variables. We already made this change for Kati, which also loads all of the same code and actually does the build, so it has been half-removed for a while. The only "UI" this implements is what I'll call "Make Emulation" mode -- it's expected that current command lines will continue working, and we'll explore alternate user interfaces later. We're still using Make as a wrapper, but all it does is call into this single Go program, it won't even load the product configuration. Once this is default, we can start moving individual users over to using this directly (still in Make emulation mode), skipping the Make wrapper. Ideas for the future: * Generating trace files showing time spent in Make/Kati/Soong/Ninja (also importing ninja traces into the same stream). I had this working in a previous version of this patch, but removed it to keep the size down and focus on the current features. * More intelligent SIGALRM handling, once we fully remove the Make wrapper (which hides the SIGALRM) * Reading the experimental binary output stream from Ninja, so that we can always save the verbose log even if we're not printing it out to the console Test: USE_SOONG_UI=true m -j blueprint_tools Change-Id: I884327b9a8ae24499eb6c56f6e1ad26df1cfa4e4
