Looks like "[PATCH 7/9] Gccgo port to s390[x] -- part I" [1,2] broke it.
The definitions from bits/stat.h are:
--cut here--
/* Nanosecond resolution timestamps are stored in a format equivalent to
'struct timespec'. This is the type used whenever possible but the
Unix namespace rules do not allow the identifier 'timespec' to appear
in the <sys/stat.h> header. Therefore we have to handle the use of
this header in strictly standard-compliant sources special.
Use neat tidy anonymous unions and structures when possible. */
