Draft: sysota: force external linking with clang
When sysota is built with toolchain-clang broken dynamicaly linked binary file is produced [1] if shared linking (GO_DYNLINK) is disabled. As the result strip phase of do_packages fails with [2] Sysota is built with disabled shared linking because of another bug [3] The problem with stripping can be fixed with specifying external linker for clang toolchain (by default Go swutched to internal linker on 64bit arches if -pie has been specified since version 1.15 [4] ). Limiting this change to clang only to be safe.
