I'm attempting to cross-compile libstdc++-v3 from FreeBSD 9.0 to ARMv5 using gcc 4.6.3 (the latest of the 4.6 series) and I'm hitting this error too. In fairness, it's a patched version of gcc 4.6.3 to target Android on ARM. This was an attempt to extend the existing lang/gnatdroid-armv5 cross-compiler port on FreeBSD to include c++, objC, and Fortran. The commonality between the original report and mine is the cross-compile. maybe that's the case where the configure test is lacking.
