Just spent half a day debugging that problem. For me, it was
caused by bad values of some environment variables. I had
actually been debugging an ICE in an lto test case, running the
compiler with -v fo figure out the actual command that caused the
problem. So I copied the commands setting the environment
variables COLLECT_GCC, COLLECT_GCC_OPTIONS and COMPILER_PATH to
the shell and then forgot about them. After that, the gcc build
failed with the above error message. Closing the shell and
staring a new one fixed the problem.
