LAPACK failures are diminishing!

[Steve Kargl]

With Richard Henderson's recent commit to fix complex division, the
LAPACK test programs are much happier.  On amd64-*-freebsd, I'm getting

troutmask:sgk[35] grep -i fail testing/*out
testing/csep.out: CST drivers:      2 out of  11664 tests failed to pass the threshold
testing/csep.out: CST:              1 out of   4662 tests failed to pass the threshold
testing/csep.out: CST drivers:      1 out of  11664 tests failed to pass the threshold
testing/dgd.out: DXV drivers:     200 out of   5000 tests failed to pass the threshold
testing/sgd.out: SXV drivers:      37 out of   5000 tests failed to pass the threshold
testing/ssep.out: SST drivers:      1 out of  14256 tests failed to pass the threshold
testing/ssvd.out: SBD:              1 out of   5510 tests failed to pass the threshold
testing/zgd.out: ZXV drivers:      24 out of   5000 tests failed to pass the threshold

This is a significant improvement.

More importantly, one of my research codes that uses blas/lapack
to compute the determinant of complex matrices is now functioning!
