The clickhouse program links to LLVM and to the clickhouse library, that also
links to LLVM. When the library is shared but LLVM is static, LLVM gets linked
into the program twice (once via the library and once directly), which causes
this error when running clickhouse:
: CommandLine Error: Option 'x86-use-base-pointer' registered more than once!
LLVM ERROR: inconsistency in registered CommandLine options
A common LLVM installation provides static component libraries and a shared
libLLVM. Linking to libLLVM when libclickhouse is shared solves this issue.
