The GNUmakefile had 1295 lines and mixed build configuration, LLVM bootstrapping, device generation, four test suites, the smoke tests, release packaging, and lint tools. The smoke tests alone were 500 lines. Move each part into its own file in make/ and include them from GNUmakefile. config.mk must be included first because the other files use its variables in immediate assignments and conditionals. There is no change in behavior. The parsed make database is identical for the default build and for ASSERT=1, STATIC=1, XTENSA=0, STM32=0, WASM=0, and CROSS=aarch64-linux-gnu, except for MAKEFILE_LIST and the .PHONY list, which now also includes targets that were phony but not declared. The Dockerfile copies GNUmakefile alone before it builds LLVM, to keep that layer independent of the source tree. It must copy make/ too.
