Bugfix for boost.locale compilation error on Jetson AGX Xavier (#221)

Otherwise, bazel build [Boost.Locale hello.cpp]
(https://www.boost.org/doc/libs/1_68_0/libs/locale/doc/html/hello_8cpp-example.html)

With BUILD file

```
load("@rules_cc//cc:defs.bzl", "cc_binary")

package(default_visibility = ["//visibility:public"])

cc_binary(
    name = "hello",
    srcs = ["hello.cpp"],
    deps = [
        "@boost//:locale",
    ],
)
```

will fail:
