* This is designed to test strerorr and strerror_l's ability to react properly
* to being in various locales. This also serves as a regression test for
* illumos#6133.
*
* For this test, we utilize the poorly named 'zz_AA.UTF_8' locale which
* was created because it actually has a translation! It 'translates'
* the string:
*
* "No such file or directory" -> "It's a trap!"
*
* It's otherwise a boring en_US.UTF-8 locale under the hood.
*
* We explicitly want to verify the following cases:
*
* + strerror() honors the global locale before uselocale
* + strerror() honors the per-thread locale
* + strerror_l() always reflects the chosen locale
