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

[Toan Pham]

Thiago,


I am running two parallel builds at the moment, and they are:


1.  32 bit LXC container (ubuntu 16.04 32bit)
     The build is still compiling chronium web-engine for the last an hr
and a half.  So far, I haven't had much problem w/ this one except that I
had to comment out a few lines in qtwebengine/qtwebengine.pro to get the
build started.



2.  32bit inside T2SDE sandbox (ref. http://t2sde.org)

      This build stopped here:

Please let me know if you know what went wrong w/ the second build.
