Okay, I tried again, but with:

configure --enable-cxx --build=none-unknown-linux-gnu

to build with just the plain vanilla.

make succeeds.

make check fails with an ld error.

last few lines:

ranlib .libs/libtests.a

This doesn't seem like a compiler bug. Same everything except the
option I used for the configure script.
