No need to add code: 
add_project_link_arguments('-lasan', language: 'c')
dpdk_extra_ldflags += '-lasan'

The app compiled by clang will fail to run

Set the macro directly:
dpdk_conf.set10('RTE_MALLOC_ASAN', true)

All code:
if get_option('b_sanitize') == 'address'
    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

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