[Joel Sherrill]

Some long overdue notes since I hit this problem
and may have some ideas now.

And that's because RTEMS uses the standard libm.a
and there is no body.

I hit this on the trunk.

Please remove the --program-prefix.

I got this error when I had a --enable-multilib but you don't have that. :(

Check your build log.  Is the a-numaux being compiled with the
