util/kconfig: Add pre-built parser
It avoids the dependency on bison/flex, minimally speeds up the build and also works around weird race conditions in some versions of bison that need more investigation. The issue this avoids manifests as a build error when creating parser.tab.c: input in flex scanner failed make: *** [util/kconfig/Makefile.inc:66: build/util/kconfig/parser.tab.c] Error 2 Since the error happens within bison the alternative would be to make bison part of our crossgcc environment to ensure that no broken OS build is used.
