    clang: Fix -gz=zlib options for linker

    Clang commit ccb4124a4172bf2cb2e1cd7c253f0f1654fce294:

    Fix -gz=zlib options for linker

    gcc translates -gz=zlib to --compress-debug-options=zlib for both
    assembler and linker but clang only does this for assembler.

    The linker needs --compress-debug-options=zlib option to compress the
    debug sections in the generated executable or shared library.

    Due to this bug, -gz=zlib has no effect on the generated executable or
    shared library.

    This patch fixes that.

    Clang commit 462cf39a5c180621b56f7602270ce33eb7b68d23:

    [Driver] Fix -gz=zlib options for linker also on FreeBSD

    ccb4124a4172 fixed translating -gz=zlib to --compress-debug-sections for
    linker invocation for several ToolChains, but omitted FreeBSD.
