[CMake] PIE-pie_off and CMP0083-cmp0083_new fail for openSuse Leap 15.0

[Marc CHEVRIER]

clearly, from what shown on http://paste.opensuse.org/14067189, c++ compiler from OpenSuse Leap is buggy.
Expected output from readelf for executable tests_1 is « Elf file type is EXEC (Executable file) » which is not the case. Option -no-pie is not taken into account.

This explains the failures for some PIE tests.
