To close the loop here, I replaced -DBOOTSTRAP_LLVM_ENABLE_LTO

by -DLLVM_ENABLE_LTO and it fixed this issue. this works because I am still
using gcc-8 but it will fail with gcc 9 because of
https://bugs.llvm.org/show_bug.cgi?id=43193
and https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=939472 (which is 
probably the same) as this bug.

A similar bug has been reported here:
https://bugs.llvm.org/show_bug.cgi?id=43722

Cheers
