Just before retrying the bootstrap, I grabbed each of the 3 prerequisites from the "infrastructure" directory on the gnu ftp server. Built and installed them with no-argument "configure" so they end up in /usr/local/. Did the same with gcc.
My build system doesn't have LD_LIBRARY_PATH defined so whatever is the Linux default would apply. Perhaps I should change that. But it seems strange that configure finds the prerequisites and then ends up generating makefiles that produce a compiler that can't find those things, even when it's built into the same /usr/local as the libraries it depends on.
