Description: call of overloaded ‘abs(double)’ is ambiguous
 AMF Tools are integrated into Repsnapper and currently FTBFS on
 Yakkety. Any abs(double) must be replaced by std::abs(double).
 While the expectation was for it to affect all arches, for some
 reason only PPC64EL and PPC are being affected.
