Subject: [PATCH] Fix compilation with GCC 6

  qtcharts/tests/manual/chartwidgettest/mainwidget.cpp:211:74: error: call of overloaded ‘abs(double)’ is ambiguous
                 newColumn.append(abs(sin(3.14159265358979 / 50 * i) * 100));

The file included <cmath>, but used C's math.h abs(), which
is integer-only.                                                                        ^
