It's best to also add --enable-64-bit-bfd

Broken autoconf install?  Zapped aclocal.m4, or other .m4 files, possibly
including those in bfd parent dir?  Does cvs diff show anything
interesting?

Possibly a broken sed, but more likely just more autoconf damage.  Does
your build/bfd/dep.sed look reasonable?
