Which version of Octave are you using and what version of autoconf was
used to generate the configure script?  I think it should work if you
use autoconf 2.59.

Also, you don't really need the --with-f77=ifort option.  The
following should be sufficient:

 ./configure --prefix=... --enable-64 CXX=icc CC=icc F77=ifort FFLAGS="-i8 -O"

BTW, do you really want --prefix=/home/octave?  Will you be able to
write to that directory?
