math/{lapack*,cblas*}: update netlib BLAS to 3.12.0
This drops the static libraries along with the custom patches for those. Also,
the hack of linking CBLAS as Fortran library as opposed to C is gone. If this
breaks some NetBSD install, it should be investigated and fixed properly.
The only patch now is one unified one I already submitted for inclusion
upstream. Maybe soon we can drop any patches. Yay!
Here is a list of upstream changes:
LAPACK 3.12.0: What’s new
Download: lapack3.12.0.tar.gz
This is a major release and also addressing multiple bug fixes.
Dynamic Mode Decomposition (DMD)
xGEDMD computes the Dynamic Mode Decomposition (DMD) for a pair of
data snapshot matrices. For the input matrices X and Y such that Y =
A*X with an inaccessible matrix A, xGEDMD computes a certain number
of Ritz pairs of A using the standard RayleighRitz extraction from
a subspace of range(X) that is determined using the leading left
singular vectors of X. Optionally, xGEDMD returns the residuals of
the computed Ritz pairs, the information needed for a refinement of
the Ritz vectors, or the eigenvectors of the Exact DMD.
xGEDMDQ does the same as xGEDMD but uses a QR factorization based
compression of the data.

Truncated QR with Column Pivoting
The routine computes a truncated (rank K) or full rank Householder
QR factorization with column pivoting of a real MbyN matrix A
using Level 3 BLAS.
The truncation criteria (i.e. when to stop the factorization) can
be any of the following: (1) The input parameter KMAX, the maximum
number of columns KMAX to factorize; (2) The input parameter ABSTOL,
the absolute tolerance for the maximum column 2norm of the residual
matrix R22(K); (3) The input parameter RELTOL, the tolerance for the
maximum column 2norm matrix of the residual matrix R22(K) divided by
the maximum column 2norm of the original matrix A, which is equal
to abs(R(1,1)). The algorithm stops when any of these conditions is
first satisfied, otherwise the whole matrix A is factorized.

Reciprocal Scaling of complex vectors
[C/Z]RSCL multiplies an nelement complex vector x by the complex
scalar 1/a. This is done without overflow or underflow as long as
the final result x/a does not overflow or underflow.

of a complex number", Weslley da Silva Pereira,

Log message:
mk/blas.bl3, Netlib and OpenBLAS packages, NumPy: C fixup and 64 bits
This delivers 64 bit index BLAS libraries alongside 32 bit ones. This is often
called ILP64 in the BLAS world, as opposed to LP64 where integers are 32 bit
due to the Fortran default integer type, not to be confused with the basic
system ABI used by C. For really large vectors on modern machines, you want
an 'ILP64' BLAS and layers on top of it.
In preparation of better support for vendor BLAS libraries, I had to realize
that you better use the C interfaces supplied by them, not the netlib one
strapped on. A simple reason of practicability: The vendor blas libraries,
just like openblas, like to ship all symbols in one library, so you get them
whether you want it or not. Also implementations may skip Fortran and implement
the underlying functionality directly in C anyway, so one might skip a
layer of indirection. Future will tell if other layers will follow. We still
have the framework of individual layers from Netlib to combine with certain
implementations that miss them (Accelerate framework comes to mind, which
needs further work).
The framework of netlib reference packages for the separate libraries
is instructive and helps keeping things small when you not need all of them.
The installation location of the headers is now in a subdirectory to be able
to have 32 and 64 bit variants independently. The 32 bit ones are linked to
${PREFIX}/include to keep the old picture. We could be brave and remove
those, but there is some value in a build just trying lcblas and
inclusion of <cblas.h> to be happy.
There is one blas.buildlink3.mk that is supposed to be used only once and
so avoids a combination of conflicting libraries (as the 64 bit index symbols
have the same names as the 32 bit ones).
Basic usage for getting LAPACK+BLAS is still the same as before. You get
CBLAS and LAPACKE by setting BLAS_C_INTERFACE=yes in the package. The 64 bit
indices are selected via BLAS_INDEX64=yes.
Due to the special nature of the Accelerate framework, a package has to
explicitly indicate support for it and it will also not appear on the
list of implementations by default. The reason is that it does provide
mainly CBLAS and CLAPACK (another version of C interface to LAPACK, f2cbased)
and BLAS/LAPACK with f2c/g77 calling conventions. A default build with
gfortran would not like that
This commit also fixes up math/pynumpy and math/pynumpy16 to follow the
new scheme, as that are the only packages directly affected by the change
in CBLAS providership.

Log message:
math/lapack, math/cblas, math/lapacke: Remove premature cmake files from install
Those cmake config files are not useful for us and they are incorrect
for the upcoming 64bitindex variants. Also, we could switch back
to the Makefile build from cmake in future. Let's treat the question of
CMake as implementation detail of the packages.
The actual use is via mk/blas.bl3 in pkgsrc and pkgconfig. There isn't
even added value in these files, were they to be correct. CMake builds
can use pkgconfig just fine.
