returning the same modid over and over again if there is a gap and

elf: Fix glibc-hwcaps priorities with cache flags mismatches [BZ #27046]
If lib->flags (in the cache) did not match GLRO (dl_correct_cache_id),
searching for further glibc-hwcaps entries did not happen, and it
was possible that the best glibc-hwcaps was not found. By accident,
this causes a test failure for elf/tst-glibc-hwcaps-prepend-cache
on armv7l.
This commit changes the cache lookup logic to continue searching
if (a) no match has been found, (b) a named glibc-hwcaps match
has been found(), or (c) non-glibc-hwcaps match has been found
and the entry flags and cache default flags do not match.
_DL_CACHE_DEFAULT_ID is used instead of GLRO (dl_correct_cache_id)
because the latter is only written once on i386 if loading
of libc.so.5 libraries is selected, so GLRO (dl_correct_cache_id)
should probably removed in a future change.

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).

time: Add 64-bit time support for getdate
The getdate is basically a wrapper localtime and mktime. The 64-bit
time support is done calling the 64-bit internal functions, there is
no need to add a new symbol version.
Checked on x86_64-linux-gnu and i686-linux-gnu.

y2038: Add __USE_TIME_BITS64 support for socket-constants.h
It is only used for !__USE_MISC, the default way uses the kernel
headers. The patch also adds the SO_TIMESTAMP, SO_TIMESTAMPNS, and
SO_TIMESTAMPING which uses new values for 64-bit time_t kernel
interfaces.
The __USE_TIME_BITS64 is not defined internally yet, although the
internal header is used when building the 64-bit stat implementations.
