When MaterialX is linked into multiple dylibs/so, symbols should be hidden so that they step on each other.
Add:
-fvisibility-inlines-hidden
-fvisibility=hidden

Fix missing basis orthogonalizations in GLSL backend (#1177)
fefce08 
I've encountered shading artifacts in normal mapped MaterialX materials, and upon closer inspection I believe that these are caused by the missing basis orthogonalizations @Tellusim brought to attention in PR #1049.

However, instead of using a second normalize(cross(..)) call, I've applied the Gram-Schmidt algorithm.
