This test failure is pre-existing on master and is not introduced by this series. I verified that vanilla master (commit d3e7d81adc8, the baseline cited by the CI report) produces identical output to the patched build for the Egypt walk in test_egypt() — the diff is empty.
The test's hardcoded expected output expects ambiguous local_info results at certain EEST→EET fall-back transitions (2003, 2005, 2007, 2009, 2010), but the current master code produces two consecutive unique EET intervals instead (a 1-hour interval followed by the long winter interval, same offset/save/abbrev). This looks like a pre-existing consequence of the merge block in _M_get_sys_info being #if 0'd out.
--Álvaro.

Hi Alvaro, Hi All,
Yes, this was an issue in Linaro CI. It should be fixed now.
