Single failed test

Single failed test for:

BulletCollisionTest.GjkEpaSphereSphereRadiusNotFullMarginDistance

on Ubuntu 14.04 with ATI Radeon 6900 series . Not the same problem I had last time around, so I thought it would be worth a mention.

I'm using cmake 2.8.12, gcc 4.8, the AMDAPP-SDK-3.0-Beta, and Catalyst-
Omega-14.12 drivers. I don't use the .deb versions of the drivers because I can never seem to get
them to work.

Anyway, the problem goes like this:

The difference between btFabs(btScalar(i-z))-btScalar(j)-ssd.m_radiusB and distInfo.m_distance is 
0.10201358795166016, which exceeds abs_error, where btFabs(btScalar(i-z))-btScalar(j)-
ssd.m_radiusB evaluates to -8.6000003814697266, distInfo.m_distance evaluates to 
-8.4979867935180664, and abs_error evaluates to 0.10000000149011612.

So the test is really close to being within the permissible error.

Everything else is working beautifully.
