 don't build with -ansi
 -ansi is for C++ equivalent to -std=c++98
 .
 Qt 5.7 uses C++11 features in its headers, resulting in
 compile errors when trying to use these headers in C++98 mode.
 .
 Removing -ansi fixes the bug, depending on upstream policy
 building with -std=c++11 (or -std=c++14) instead of -ansi
 might be preferred by upstream with gcc versions that
 support these standards.
