1. Excerpted from: https://github.com/ARM-software/LLVM-embedded-toolchain-for-Arm/blob/main/samples/src/cpp-baremetal-semihosting-prof/proflib.c
2. Since llvm profile supports more than just gcov, and some features have not yet been explored, two clang gcov implementations are supported after this patch
3. Using this lib only supports the gcov compilation options of "-fprofile-instr-generate -fcoverage-mapping"
4. This file is heavily dependent on the compiler clang version, and is currently aligned with ci, supporting 17.0.1 and below. 18 and above are not supported by this library due to different internal implementations of the compiler

Most tools used for compliance and SBOM generation use SPDX identifiers
This change brings us a step closer to an easy SBOM generation.

Will report clang: error: invalid argument 'medium' to -mcmodel=
-mcmodel=large will both support clang and gcc.

The reason for removing math.h is that undefining __GLIBC__ does not take effect. By default, sim will use the toolchain's math library and undef __GLIBC__ in the source file.

use the dynamic library .so of the binding compilation environment,
and then modify the dynamic loader of elf at runtime to run sim elf across system versions
1.add post-build for sim build
2.collect dynamic .so and dynamic interpreter
3.add execution script for the entire package sim elf
change text-segment to 0x50000000
because patchelf will modify the .dynamic section in elf,
the upward alignment of elf will be less than 0x3fffffff,
which will cause asan shadow memory overlap error

1. CONFIG_ARCH_COVERAGE has been replaced by CONFIG_SCHED_GCOV
2. Delete the SIM-specific GCOV_ALL configuration and change it to a universal configuration for all architectures

Some domains have a lot of IPv6 addresses. Because of that, it is
not possible to get the IPv4 address with getaddrinfo.
This change separate IPv4 and IPv6 cache size limit to enable to
get both IP addresses.
