When trying to build GCC 4.6.0 with Ada support, I get the following error:

It was my understanding that the pic/ subdirectory of libiberty/ was for a
PIC version of libiberty. This error occurs whether I explicitly export
-fPIC in CFLAGS or not. I have been able to build GCC 4.6.0 successfully
without Ada.
The cases where I have seen this are where somebody runs configure, runs
make, and then runs configure again in the same directory in a way that
changes whether the PIC version of libiberty needs to build. Is it
possible that that happened here?

I'm fairly certain this isn't happening, I automate my builds and start
with a fresh unpacking each time. I've looked through the build logs,
and I don't see any configure-like output after building starts. Also,
there is a file libiberty/pic/libiberty.a after the build failure,
though I don't know how to check if it has been built with PIC.
