Test case

Even simple C++ code fails to link when compiled with mmix g++ 6.1.0, binutils
2.26 and newlib 2.4.0:

$ mmix-g++ hello.cc
/usr/lib/gcc/mmix/6.1.0/../../../../mmix/bin/ld: BFD (GNU Binutils)
2.26.20160125 internal error, aborting at bfd/elf64-mmix.c:1043 in
mmix_elf_perform_relocation

Compiling with 5.3.0 (and the same binutils and newlib) succeeds.
