Didn't say that anyone was.

None of the "commands" succeeded and the output is the same as in the
original problem.  Building the shared libgcc in 4.9.2 fails with
undefined reference to dlopen.  This succeeds in 4.8.4 but there is no
info that I can see in the build l9gs I captured that indicates why
