On a Fedora 26 system, I run configure as:
$ ../configure --with-assertions --with-lto --with-pydebug --with-address-sanitizer --disable-ipv6
My pyconfig.h contains:
/* #undef HAVE_CLOCK */
/* Define to 1 if you have the `clock_getres' function. */
/* #undef HAVE_CLOCK_GETRES */
/* Define to 1 if you have the `clock_gettime' function. */
/* #undef HAVE_CLOCK_GETTIME */
/* Define to 1 if you have the `clock_settime' function. */
/* #undef HAVE_CLOCK_SETTIME */
/* Define if the C compiler supports computed gotos. */
/* #undef HAVE_COMPUTED_GOTOS */
When this happens, __PyTime_FromTimespec is undefined in pytime.c:747.
../Python/pytime.c:747:9: error: implicit declaration of function ‘_PyTime_FromTimespec’; did
you mean ‘_PyTime_FromTimeval’? [-Werror=implicit-function-declaration]
if (_PyTime_FromTimespec(tp, &ts, raise) < 0)
^~~~~~~~~~~~~~~~~~~~
_PyTime_FromTimeval

OK, the problem was the missing libasan which made quite a few checks fail.
We should check for libasan before all other checks, when compiling with --with-address-sanitizer.
