Hello, this is an example of failure during configure step
```
configure:19582: checking whether a simple qt program can be built
configure:19593: g++ -o conftest -g -O2 -fdebug-prefix-map=/<<PKGBUILDDIR>>=. -specs=/usr/share/dpkg/pie-compile.specs -fstack-protector-strong -Wformat -Werror=format-security -I/usr/include/i386-gnu/qt5/QtCore -I/usr/include/i386-gnu/qt5 -fpic -specs=/usr/share/dpkg/pie-link.specs -Wl,-z,relro -Wl,-z,now conftest.cpp -lQt5Core >&5

```
and this is a trivial patch that fixes the problem in Debian and Ubuntu, where pie is default
Description: Use -fPIC instead of -fpic.
