Fix shared hermetic builds on Arch linux

On Arch linux clang uses PIE by default, and so it requires Scrt1.o:

    $ /usr/bin/clang++ --target=x86_64-linux-gnu --sysroot=/src/ch/clickhouse/cmake/linux/../../contrib/sysroot/linux-x86_64/x86_64-linux-gnu/libc --gcc-toolchain=/src/ch/clickhouse/cmake/linux/../../contrib/sysroot/linux-x86_64 --gcc-toolchain=/src/ch/clickhouse/cmake/linux/../../contrib/sysroot/linux-x86_64 -std=c++20 ... -o base/base/tests/dump_variable ...
    clang version 13.0.0
