build: fix _Noreturn compilation failure

Fix a build failure seen on gcc 3.4 on Solaris 10 at least.

* src/crctab.c: Ensure we include config.h for all compilation units.
This is now required for new _Noreturn usage in gnulib for stdint.h.
* src/cksum.c: Update generation code to ensure config.h included.
* cfg.mk: Remove crctab.c exclusion from the config.h check.
