util/kconfig: Uprev to Linux 5.13's kconfig This was originally several commits that had to be squashed into one because the intermediate states weren't able to build coreboot: - one to remove everything that wasn't our own code, leaving only regex.[ch], toada.c, description.md and Makefile.inc. - one to copy in Linux 5.13's scripts/kconfig and adapt Makefile.inc to make the original Makefile work again. - adapt abuild to use olddefconfig, simplifying matters. - apply patches in util/kconfig/patches. - Some more adaptations to the libpayload build system. The patches are now in util/kconfig/patches/, reverse applying them should lead to a util/kconfig/ tree that contains exactly the Linux version + our own 5 files.

util/kconfig: Simplify dependencies for parser.tab.* With parser.tab.h depending on parser.tab.c it's possible for make to initiate the creation of parser.tab.c, then try to compile it, even though parser.tab.h is still missing. This isn't normally an issue yet because bison creates them both at a time but with pre-compiled files this will become a problem. Pattern rules support (until recently as a special case that no other type of rule could implement) multiple targets that are actually treated as "one command creates multiple output files" so use that to state the relationship properly.
