(__ASSUME_CLONE_THREAD_FLAGS): Set on sparc when 2.5.64 and later.
(__ASSUME_TGKILL): Set on sparc when 2.6.1 and later, simplify
expression.
(__ASSUME_FADVISE64_64_SYSCALL): Set on sparc when 2.6.1 and
later.
fopen should set the FD_CLOEXEC flag if requested evenif the kernel does
not support an aotmic operation.
freopen should reuse the file descriptor for the stream. This is
especially important for calls to change the standard streams (stin,
stdout, stderr).
The syscall conventions on some Linux archs prevented F_GETOWN from working
correctly in some situations. This can be rectified when using the new
F_GETOWN_EX command.

__ASSUME_COMPLETE_READV_WRITEV.
* sysdeps/unix/sysv/linux/readv.c: No need for userlevel fallback
with modern kernels.
* sysdeps/unix/sysv/linux/writev.c: Likewise.
* sysdeps/posix/readv.c: Since read is a cancellation point we have
to free a possible malloced buffer in case of cancellation.
* sysdeps/posix/writev.c: Likewise for write.
