Log message:
math/lapack: Restore build on DragonFly

Linking lapack with the gold linker fails with this error:
fatal error: --sysroot=: must take a non-empty argument

DragonFly has been using the gold linker by default for a while now.
Since I don't have time to track down this linking problem, I'm going
to restore the build on DragonFly by setting an environment variable
that forces DF to use the classic GNU linker instead.

This was already fixed on math/blas which uses the lapack common
makefile, so just relocate the fix to lapack.

Log message:
Updated lapack to 3.6.1.

 LAPACK 3.6.1: What’s new

[Mark Gates, UTK] blocked back-transformation for the non-symmetric eigenvalue \ 
problem

It blocks NB gemv calls into one gemm call inside trevc. To do
that, it needs a new routine, trevc3, because unfortunately the
lwork was not passed into trevc. Attached is the performance speedup
for dgeev. It gives a nice 1.5x speedup for N=20000, and that
appears to still be increasing with N. This is not the improvements
that Greg Henry recently provided for doing the triangular solves
as BLAS-3 instead of BLAS-1. That will take a while to process,
but we expect another, even larger increase in performance when
those changes are applied. This also does not include doing multiple
(BLAS-1) triangular solves in parallel, which is available in MAGMA,
since that requires OpenMP or pthreads.
