Ronald Niederhagen / Mbed 2 deprecated Testcase_RTC

with gcc-arm-none-eabi-7-2017-q4-major the default typedef of time_t is "long long int". older releases typedef time_t as "long int". mbed lib cannot handle this correctly This applies to exported projects as "GCC (ARM-Embedded)"

This testcase demonstrates the incompatibility of time_t when using gcc-arm-none-eabi-7-2017-q4-major.; The symptom is apparent with "sizeof(time_t)"; The 2017-q4 release shows 8 "long long int"; Older releases show 4 "long int"
