This macro exists since Linux 2.6.25 [1] and is defined in glibc
since 2.14 [2] for sparc and most supported architectures.
RLIMIT_RTTIME has been added later for mips [3] and alpha [4].
For example, RLIMIT_RTTIME is needed to build qemu 7.0.0 with
Linux user-land emulation support [5].

Since Linux 3.11, O_TMPFILE allows to create unnamed files that can be
linked later on. It is internally defined as (O_TMPFILE | O_DIRECTORY)
to make it fail on old kernels.
Copying definitions from glibc for O_TMPFILE is not enough to support
O_TMPFILE; The open() wrapper also need to pass the mode when the flag
contains O_TMPFILE, otherwise, it will pass mode 000 which will succeed
but yield unexpected results.
openat() is curiously not affected since it passes the mode
unconditionally..

Rename various spare fields in structs to include a namespace
This should avoid accidental clashes with uses of the __unused symbol
in upstream projects. eg currently it causes a compile error in dhcpcd 8.x
due to their re-use of the __unused symbol as a macro
This follows the style of glibc which does something equivalent

we need to handle Linux kernel change, which removed stat64 family from default syscall set.

Update from linux/arch/sparc/include/uapi/asm/uctx.h

Sync with GNU C library and consolidate duplicate non
architecture specific defines.
MAP_UNINITIALIZED is only defined to 0x4000000 and used by
the Linux kernel when CONFIG_MMAP_ALLOW_UNINITIALIZED is enabled.
CONFIG_MMAP_ALLOW_UNINITIALIZED is only available for nommu.
See Documentation/nommu-mmap.txt.

No NPTL, no LDSO support.
Bootup with Busybox Ash in Qemu working.
Testuite shows only two failures, but mksh continue/break
support doesn't work.
