Minor configure item and Fedora 9

[Michael D Godfrey]

When compiling on a new Fedora 9 x86 system I noticed
something that I had noticed in the past:

When compiling release-3-0.x:
If suitesparse and suitesparse-devel (both i386 ans x86)
are installed, but blas and blas-devel are not installed, the
./configure missing libraries message says that
CHOLMOD library is missing.  I would be helpful if the
test for blas (not a part of suitesparse) were done separately,
and reported if it is missing.

The only other problems with Fedora 9 were:
1. hdf5-1.8.0-1.fc9 is not compatible with Octave.  They have
    changed some calls so that arguments do not match.
2. The f9 rpm for blas is currently broken. It does not install
    the /usr/lib64 libs correctly.  Since this is the same blas as
    for f8, that an be used (or just copy the correct libraries
    from an f8 (x86) system.
make check ran with 3 errors.

For some reason, the ./configure of the main (default)
branch is going very wrong: does not find suitesparse libs
and dies on test for  sizeof(short).  I will try to discover why.
