Hello,

This looks like an issue in the way the basic build infrrastructure on x32
is set-up.

Looking at config.log we find that {C,CXX,LDFLAGS} all contain
-specs=/usr/share/dpkg/pie-compile.specs on x32 and we get this error:

configure:22249: checking whether a simple qt program can be built
configure:22260: g++ -o conftest -g -O2 -ffile-prefix-map=/<<PKGBUILDDIR>>=. -specs=/usr/share/dpkg/pie-compile.specs -fstack-protector-strong -Wformat -Werror=format-security -fcf-protection -DQT_CORE_LIB -I/usr/include/x86_64-linux-gnux32/qt5/QtCore -I/usr/include/x86_64-linux-gnux32/qt5  -fpic -specs=/usr/share/dpkg/pie-link.specs -Wl,-z,relro -Wl,-z,now conftest.cpp -lQt5Core  >&5
In file included from /usr/include/x86_64-linux-gnux32/qt5/QtCore/qcoreapplication.h:43,
                 from /usr/include/x86_64-linux-gnux32/qt5/QtCore/QCoreApplication:1,
                 from conftest.cpp:48:
/usr/include/x86_64-linux-gnux32/qt5/QtCore/qglobal.h:1287:4: error: #error "You must build your code with position independent code if Qt was built with -reduce-relocations. " "Compile your code with -fPIC (and not with -fPIE)."

The autoconf test *does* use -fpic but
-specs=/usr/share/dpkg/pie-link.specs sets PIE and stuff breaks.
