No. As I have written already [1] & [2], there is no need for the
filename and the soname to be related at all

What I think the problem could be here is that libblas and
libcblas/libgslcblas provide two different interfaces; clapack finds
itself fine with libblas, but it doesn't find the required symbols in
libcblas, so --as-needed discards the linking.

I don't think I have the libraries around, maybe the tinderbox.
Otherwise prod me on IRC/Jabber, it's faster, then we can post the
results.
