Bisecting showed this was introduced in binutils commit 26e3a0c [1],
which turns on .init_array/.fini_array support by default.  It makes
most C++ executables crash at startup, on 9.x, since support for this
was not fully merged back to stable/9.

I think Baptiste is working on a fix.  It is probably best to configure
binutils on 9.x with --disable-initfini-array.
