While Andrew pushed the current patch set, Metze pointed out that it
didn't solve the issue with CONFIG_SET() still reporting undefined
defines are set if they were stored in the cache as '0'.

Attached patch should fix the issue. On FreeBSD 11.2 I now have:

$ egrep '(HAVE_BSD_STRTOLL|INCOHERENT_MMAP|WORKING_STRPTIME)' bin/default/include/config.h bin/c4che/default_cache.py
bin/default/include/config.h:#define HAVE_BSD_STRTOLL 1
bin/default/include/config.h:/* #undef HAVE_WORKING_STRPTIME */
bin/default/include/config.h:/* #undef HAVE_INCOHERENT_MMAP */
bin/c4che/default_cache.py:HAVE_BSD_STRTOLL = 1
bin/c4che/default_cache.py:HAVE_INCOHERENT_MMAP = ()
bin/c4che/default_cache.py:HAVE_WORKING_STRPTIME = ()

Subject: [PATCH] buildtools/wafsamba: undefine a define for a failed test
 unless asked to keep it

If conf.CHECK_CODE() is called without `always=True` and the test has
failed, undefine the define already set to '0' by conf.check_code().

This restores expectations that undefined symbols are not considered to
be set by CONFIG_SET() method.
