amd64-unknown-freebsd8.3 doesn't like this, I'm afraid:

configure: visibility supported: yes
checking for rdrand support in assembler... eval: ${+...}: Bad substitution
gmake[2]: *** [configure-stage1-target-libstdc++-v3] Error 2

Note, this is BSD sh, not bash.  I'll admit that I had a look, and
did not find the culprit right away.
