Right now it works for host platforms because of gcc package, that
includes gcc-cross sysroot.
Use bundled sysroot from contrib instead.

Public flags, especially -Wxx (i.e. -Wno-XX) can hide some warnings,
that had been added in the main cmake rules of ClickHouse.
This patch had been tested manually with the following patch:
```patch

And cmake gave:

We currently only log a compiler-generated "build id" at startup which
is different for each build. That makes it useless to determine the
exact source code state in tests (e.g. BC test) and from user log files
(e.g. if someone compiled an intermediate version of ClickHouse).
Current log message:
Starting ClickHouse 22.10.1.1 with revision 54467, build id: 6F35820328F89C9F36E91C447FF9E61CAF0EF019, PID 42633
New log message:
Starting ClickHouse 22.10.1.1 (revision 54467, git hash: b6b1f7f763f94ffa12133679a6f80342dd1c3afe, build id: 47B12BE61151926FBBD230DE42F3B7A6652AC482), PID 981813
Right now LINKER_NAME contains version so it does not work:
Aug 27 13:02:10 -- Using linker: /usr/bin/ld.lld-14
Without this patch:
$ time gdb ~/ch/clickhouse/.bld-release/programs/clickhouse -batch
real 1m20.564s
user 1m18.622s
sys 0m1.940s
$ time lldb-13 clickhouse -batch
real 0m9.353s
user 1m31.035s
sys 0m8.346s
With:
$ time gdb clickhouse -batch
real 0m4.769s
user 0m3.969s
sys 0m0.800s
$ time lldb clickhouse -batch
real 0m6.703s
user 0m45.383s
sys 0m4.934s
So by just adding 4.15MiB to the binary size, gdb start up time improved
17 times.
