Thanks, and nicely included your libcheck.a, which contains the LTO objects
triggering this bug.  After building myself a new gcc-8 (debugging LTO linker
problems requires using the same compiler) I was able to reproduce the problem
with current master binutils, and binutils-2.32.  For future reference, this
was the linker invocation I used:  (prev-gcc because gcc was still
bootstrapping!)
