AIUI many tegra devices don't support neon, I wonder if a neon
instruction is being used either because of incorrect compiler settings
or because of incorrect inline assembler code.
If this was happening on regular linux i'd suggest using gdb to get a
backtrace and a dissasembly of the sigill location but i'm not sure how
possible that is on andriod or how easy it is to get a suitable tegra
device running regular linux to experiment on.
