RNDR and RNDRRS instructions. Provide detection functions for RNDR and
RNDRRS getauxval.

OpenSSL assumes AT_HWCAP = 16 (as on Linux), but on FreeBSD AT_HWCAP = 25
Switch to using AT_HWCAP, and setting it to 16 if it is not defined.
OpenSSL calls elf_auxv_info() with AT_CANARY which returns ENOENT
resulting in all ARM acceleration features being disabled.

We received analytics that devices of the device family Oppo A37x
are crashing with SIGILL when trying to load libcrypto.so.
These crashes were fixed by using the system-supplied getauxval function.

thus relying on native api instead.

MIDR_EL1 system register exposes microarchitecture information so that
people can make micro-arch related optimization such as exposing as
much instruction level parallelism as possible.
MIDR_EL1 register can be read only if HWCAP_CPUID feature is supported.

Having a weak getauxval() and only depending on GNU C without looking
at the library we build against meant that it got picked up where not
really expected.
So we change this to check for the glibc version, and since we know it
exists from that version, there's no real need to make it weak.

When running iOS application from command line it's impossible to
get past the failing capability detection. This is because it's
executed under debugger and iOS debugger is impossible to deal with.
[If Apple implements SHA512 in silicon, it would have to be detected
with sysctlbyname.]

Capability probing by catching SIGILL appears to be problematic
on iOS. But since Apple universe is "monocultural", it's actually
possible to simply set pre-defined processor capability mask.

This facilitates "universal" builds, ones that target multiple
architectures, e.g. ARMv5 through ARMv7. See commentary in
Configure for details.
