Need to link -lasan when using gcc, but don’t need to link when using clang. 
You added it in the v6 version comments, but need to restrict when using clang.
All code:
if get_option('b_sanitize') == 'address' or get_option('b_sanitize') == 'address,undefined'
    if cc.get_id() == 'gcc'
        asan_dep = cc.find_library('asan', required: true)
        if (not cc.links('int main(int argc, char *argv[]) { return 0; }',
                    dependencies: asan_dep))
            error('broken dependency, "libasan"')
        endif
        add_project_link_arguments('-lasan', language: 'c')
        dpdk_extra_ldflags += '-lasan'
    endif

    if exec_env == 'linux' and arch_subdir == 'x86'
        dpdk_conf.set10('RTE_MALLOC_ASAN', true)
    endif
endif
