glibc: Update to latest on 2.31 branch

There are few fixes specifically for compiling with gcc10 that are good
to have, before hitting them later

Backport build fix from master for aarch64 with gcc10

Drop CVE-2020-10029 patch its already applied on latest 2.31 branch

latest glibc 2.31 added fix for __getauxval/aarch64 issue

-Subject: [PATCH] Fix build with GCC 10 when long double = double.
-
-On platforms where long double has the same ABI as double, glibc
-defines long double functions as aliases for the corresponding double
-functions.  The declarations of those functions in <math.h> are
-disabled to avoid problems with aliases having incompatible types, but
-GCC 10 now gives errors for incompatible types when the long double
-function is known to GCC as a built-in function, not just when there
-is an incompatible header declaration.
-
-This patch fixes those errors by using appropriate
--fno-builtin-<function> options to compile the double functions.  The
-list of CFLAGS-* settings is an appropriately adapted version of that
-in sysdeps/ieee754/ldbl-opt/Makefile used there for building nldbl-*.c
-files; in particular, the options are used even if GCC does not
-currently have a built-in function of a given function, so that adding
-such a built-in function in future will not break the glibc build.
-Thus, various of the CFLAGS-* settings are only for future-proofing
-and may not currently be needed (and it's possible some could be
-irrelevant for other reasons).
-
-Tested with build-many-glibcs.py for arm-linux-gnueabi (compilers and
-glibcs builds), where it fixes the build that previously failed.
-

-Subject: [PATCH] Avoid ldbl-96 stack corruption from range reduction of
-
- pseudo-zero (bug 25487).
-
-Bug 25487 reports stack corruption in ldbl-96 sinl on a pseudo-zero
-argument (an representation where all the significand bits, including
-the explicit high bit, are zero, but the exponent is not zero, which
-is not a valid representation for the long double type).
-
-Although this is not a valid long double representation, existing
-practice in this area (see bug 4586, originally marked invalid but
-subsequently fixed) is that we still seek to avoid invalid memory
-accesses as a result, in case of programs that treat arbitrary binary
-data as long double representations, although the invalid
-representations of the ldbl-96 format do not need to be consistently
-handled the same as any particular valid representation.
-
-This patch makes the range reduction detect pseudo-zero and unnormal
-representations that would otherwise go to __kernel_rem_pio2, and
-returns a NaN for them instead of continuing with the range reduction
-process.  (Pseudo-zero and unnormal representations whose unbiased
-exponent is less than -1 have already been safely returned from the
-function before this point without going through the rest of range
-reduction.)  Pseudo-zero representations would previously result in
-the value passed to __kernel_rem_pio2 being all-zero, which is
-definitely unsafe; unnormal representations would previously result in
-a value passed whose high bit is zero, which might well be unsafe
-since that is not a form of input expected by __kernel_rem_pio2.
-
-Tested for x86_64.
