[Development] 32bit linux build of qt5.10.0 w/ webengine

[Toan Pham]

Thiago,

I am using gcc 4.8.5, but the compiler was optimized for pentium4 so all of
those vector instructions had to be disabled at build time.

BTW, I got webengine to compile successfully with several patches to
libvpx.  Now, I just ran into another brick wall with the errors attached
at the end of this email.
Here is my qt configure option:

-prefix /opt/qt5.10.0 -no-separate-debug-info -system-zlib -system-libpng
-confirm-license -nomake examples -I /usr/X11/include -release
-webengine-webrtc -qt-libjpeg -no-sse2 -no-sse3 -no-sse3 -no-sse4.1
-no-sse4.2 -no-avx -no-avx2


Please help if you know what's going on.  thanks..
