Building Octave 3.2.4 on FreeBSD 8.1

[Thomas Dean]

I built Octave 3.2.4 on FreeBSD 8.1 by making a couple changes.

arpack on FreeBSD 8.1 requires blas to resolve some symbols, causing
configure to drop arpack.

Other libs are skipped because config does not find them.  Using
environment variables can work around this.

env F77=gfortran44 CFLAGS=-I/usr/local/include LDFLAGS=-L/usr/local/lib 
./configure --with-blas=yes
