Here's one of the hacks needed. It allows configure to finish:

    sed -i 's|$AR cru|$AR $ARFLAGS|g' configure

However, it means configure is invoked like so on OS X:

    AR="/usr/bin/libtool" ARFLAGS="-static -o " configure ...

Here's another hack that appears to be needed, but the build process
dies sooner with it applied:

    sed -i 's|$AR cru|$AR $ARFLAGS|g' aclocal.m4
