Thanks for sending the log.  gcc 3.3.2 is pretty old and I don't have
a copy online.  Looking at gcc 4.0, it looks like this would happen if
gcc were configured with --with-ld=/usr/bin/ld, or if gcc were
configured with the environment variable DEFAULT_LINKER set to
/usr/bin/ld.  That would override the -B option.

Otherwise I have no explanation.
