As I said in PR, the issue has been raised in Mar, 2012 when the
x32 port was submitted. It has been decided that x32 won't conform
to tv_nsec, blksize_t, and suseconds_t as long. I don't believe we
will change them to conform to POSIX.
As for if x32 is a toy target or not, it will be decided by whether it
delivers what users are looking for, not by if tv_nsec, blksize_t, and
suseconds_t conform to POSIX.
