Florian Weimer dbb949f53d resolv: Move libanl into libc (if libpthread is in libc)
The symbols gai_cancel, gai_error, gai_suspend, getaddrinfo_a,
__gai_suspend_time64 were moved using scripts/move-symbol-to-libc.py.

For Hurd (which remains !PTHREAD_IN_LIBC), a few #define redirects
had to be added because several pthread functions are not available
under __.  (Linux uses __ prefixes for most hidden aliases, and has
to in some cases to avoid linknamespace issues.)

Adhemerval Zanella 47f24c21ee y2038: Add support for 64-bit time on legacy ABIs
A new build flag, _TIME_BITS, enables the usage of the newer 64-bit
time symbols for legacy ABI (where 32-bit time_t is default).  The 64
bit time support is only enabled if LFS (_FILE_OFFSET_BITS=64) is
also used.

Different than LFS support, the y2038 symbols are added only for the
required ABIs (armhf, csky, hppa, i386, m68k, microblaze, mips32,
mips64-n32, nios2, powerpc32, sparc32, s390-32, and sh).  The ABIs with
64-bit time support are unchanged, both for symbol and types
redirection.

On Linux the full 64-bit time support requires a minimum of kernel
version v5.1.  Otherwise, the 32-bit fallbacks are used and might
results in error with overflow return code (EOVERFLOW).

The i686-gnu does not yet support 64-bit time.

This patch exports following rediretions to support 64-bit time:

Adhemerval Zanella 605f38177d sh: Split BE/LE abilist
The fix for BZ#18231 requires new symbols only for sh4eb.  This patch
adds the required folder and files for both BE and LE abilist.  No
semantic changes are expected.

Checked with check-abi for sh4eb-linux-gnu and sh4-linux-gnu.

	* sysdeps/sh/preconfigure: Regenerate.
	* sysdeps/sh/be/sh3/Implies: New file.
