gcc49 build fails on armv7h

[Plasmodium]

I'm trying to compile gcc49 from the AUR for the Jetson TK1. Same issues with or without a clean chroot.

I'm really stuck here. Any suggestions would be much appreciated.

What is the version of current gcc?
gcc 6.1 cannot compile gcc5.X or below...(I've try last month )
If you want gcc49, you can install ubuntu14.04 to a PC and used it to do cross-compiling.
