Adhemerval Zanella Netto 98f9435f33 Linux: optimize clone3 internal usage
Add an optimization to avoid calling clone3 when glibc detects that
there is no kernel support.  It also adds __ASSUME_CLONE3, which allows
skipping this optimization and issuing the clone3 syscall directly.

It does not handle the the small window between 5.3 and 5.5 for
posix_spawn (CLONE_CLEAR_SIGHAND was added in 5.5).

Checked on x86_64-linux-gnu.
