Hmm. I have been building e500v2 toolchains with ct-ng for a little
while, and the only problems I have ran into were
--enable-target-optspace hitting an optimization issue and this c++
search path issue (the last one happened on all of my toolchains, not
just the e500v2).

I see you are using a 2125 of ctng. Could you try with at least 2141
to rule out the c++ search path issue?
