So after further investigation, both dietlibc and fnord need to be built with
an -mcpu value less than v9 or ultrasparc.  I'd added the replace-sparc64-flags
which will adjust any -mcpu=ultrasparc or -mcpu=v9 to -mcpu=v8 to the existing
dietlibc and fnord ebuilds.  You'll need to re-emerge dietlibc once it hits the
mirrors.
