- Add new kconfig target 'make mod2noconfig', which will be useful to
speed up the build and test iteration.
- Raise the minimum supported version of LLVM to 11.0.0
- Refactor certs/Makefile
- Change the format of include/config/auto.conf to stop double-quoting
string type CONFIG options.
- Fix ARCH=sh builds in dash
- Separate compression macros for general purposes (cmd_bzip2 etc.) and
the ones for decompressors (cmd_bzip2_with_size etc.)
- Misc Makefile cleanups
