It turns out the problem is not in vlc but in the creation of libQtGui
'tmp/sysroots/nitrogen6x/usr/lib/libQtGui.la' contains these lines:

   # Libraries that this one depends upon.
   dependency_libs='   -lEGL -lGAL -DLINUX=1 -DEGL_API_FB=1  -lQtCore  -lpthread '

You can't have preprocessor commands within the link/library section.  I removed
them [manually] and was able to successfully build vlc.

I looked at 'meta-fsl-arm/qt5-layer/recipes-qt/qt5/qtbase_%.bbappend' but I
could not see what to change to keep these flags out of the *.la files

Any help with that would be appreciated.
