That sounds like a configure-script-time error. I somehow borked up my
gcc profile pretty badly the other day, and the solution turned out to
be re-running:

gcc-config $SOME_PROFILE

where SOME_PROFILE is something you'll find under /etc/env.d/gcc

After that, things worked fine for me again.

(I was in the process of building an email because I was going to ask
this list for help, and I figured out the solution while building the
narrative of things I was trying and testing. It'll probably show up
as another blog post.)
