Subject: how can we test the hexagon port in mainline

Hi all,

the oldest supported gcc version in mainline is gcc 4.9.  But the only
hexagon crosscompiler I can find is the one Arnds website points to here:

https://mirrors.edge.kernel.org/pub/tools/crosstool/

which is a non-upstream gcc 4.6.1 port.  How are we supposed to even
build test hexagon code?
