Build: clean up build system, use one shared Makefile Allow everything to be built from the top level directory with just 'make', cleaned with 'make clean', and installed with 'make install'. Also support these in any particular subdirectory. Specifying 'make VERBOSE=1' will print each ld/g++/etc. command as it runs. Kernel and early host tools (IPCCompiler, etc.) are built as object.host.o so that they don't conflict with other things built with the cross-compiler. 2019-12-18 17:35:46 -06:00			`subdirs: $(SUBDIRS)`

Build: wrap make invocations with flock(1) Lock each directory before entering it so when using -j, the same dependency isn't built more than once at a time. This doesn't get full -j parallelism though, since one make child will be sitting idle waiting for flock to receive its lock and continue making (which should then do nothing since it will have been built already). Unfortunately there's not much that can be done to fix that since it can't proceed until its dependency is built by another make process. 2019-12-27 23:50:39 -06:00			`@flock $@ $(MAKE) -C $@`
