Thanks Stuart, I inferred that from qtopia-4.spec.  The problem
(specifically) with qtopia-4 that I'm seeing is when it tries to link
qvfb using g++ (the host compiler) it fails with:

g++ -fno-exceptions -o

Thinking I messed things up while adding my omap platform, I went back
and tried building it for an imx31ads (that looks to have support in
qtopia-4.spec) and it failed in the same manner (above error is quoted
from the failure on imx31ads).  Looking at the above linker command line
I'm a bit confused as to why "-lpthread" is specified 26(!!!) times -
something looks to be seriously confused.

Turns out that I was missing libxtst-dev from my build environment...

Thanks in advance.
