Previously, in #39387, this protection had been added only for linux x86_64.
And use include_guard() instead of manual if()+set().

During first run of cmake the toolchain file will be loaded twice,
- /usr/share/cmake-3.23/Modules/CMakeDetermineSystem.cmake
- /bld/CMakeFiles/3.23.2/CMakeSystem.cmake
But once you already have non-empty cmake cache it will be loaded only
once:
- /bld/CMakeFiles/3.23.2/CMakeSystem.cmake
This has no harm except for double load of toolchain will add
--gcc-toolchain multiple times that will not allow ccache to reuse the
cache.

Make ClickHouse compilable and runnable on risc-v 64
So far only basic functionality was tested (on real hw),
clickhouse server runs, exceptions works, client works,
simple tests works.
What doesn't work:
1. traces - they are always empty
2. system.stack_trace only have first frame
gcc with -nodefaultlibs does not add sanitizers library during linkage
with -static-libasan and similar, fix this, by add them explicitly.
From the gcc(1) about -nodefaultlibs:
Do not use the standard system libraries when linking. Only the
libraries you specify are passed to the linker, and options specifying
linkage of the system libraries, such as -static-libgcc or
-shared-libgcc, are ignored. The standard startup files are used
normally, unless -nostartfiles is used.
Plus checked it manually, w/o -nodefaultlibs everything works without
this explicit linkage.
After this patch UBSAN under gcc compiled successfully.
v2: freebsd and darwin
