Request to add additional flag to resolve issue : QFontDatabase: Cannot find font directory

In makeQT QT has two option either to use system font or use QT font to display fonts
in application build, using QT . I noticed that present makeQT script
is configured to use QT font. It has not caused any issue till now but i noticed
that with QT-5.9.1 , building with default makeQT script ,cause Paraview to pop
up message "QFontDatabase: Cannot find font directory" and no font appear in QT.

Configuring qt with additional flag ** -fontconfig **, resolved the issue.

I did test with SUSE-Enterprise-12SP1 using gcc-6.4.1
