Now the only way to enable Neon support is to change the mkspec. [ChangeLog][Important Behavior Changes] Qt no longer checks for support for the Neon FPU on ARM platforms at runtime. Code optimized for Neon must be enabled unconditionally at compile time by ensuring the compiler supports Neon. You may need to edit your mkspec for that.

# This mkspec is based and tested on the TrimSlice using "Ubuntu Natty (11.04) - l4t.r15.01"-release.

# It might work with other boards and releases as well.
