Isn't this when building libf2c?  Why is that built?  It was
shut off by default 2001-11 for h8300 and h8500.  Oh, I see
disabling libf2c has disappeared for h8300-*-*.  It seems a part
of 1.128 of configure.in (part of a larger import by D.J.) was
supposed to "Enable libstdc++-v3 for h8300 targets" and
accidentally enabled libf2c too.

We've been through this before, see
<URL:http://gcc.gnu.org/ml/gcc-patches/2001-11/msg00888.html>.

I'll re-apply a patch to the effect of disabling libf2c as
obvious.
