OpenBLAS 0.3.26

general:

improved the version of openblas.pc that is created by the CMAKE build
fixed a CMAKE-specific build problems on older versions of MacOS
worked around linking problems on old versions of MacOS
corrected installation location of the lapacke_mangling header in CMAKE builds
added type declarations for complex variables to the MSVC-specific parts of the \ 
LAPACK header
significantly sped up ?GESV for small problem sizes by introducing a lower bound \ 
for multithreading
imported additions and corrections from the Reference-LAPACK project:
added new LAPACK functions for truncated QR with pivoting
handle miscalculation of minimum work array size in corner cases
fixed use of uninitialized variables in ?GEDMD and improved inline documentation
fixed use of uninitialized variables (and consequential failures) in ?BBCSD
added tests for the recently introduced Dynamic Mode Decomposition functions
fixed several memory leaks in the LAPACK testsuite
fixed counting of testsuite results by the Python script

x86-64:

fixed computation of CASUM on SkylakeX and newer targets in the special
case that AVX512 is not supported by the compiler or operating environment
fixed potential undefined behaviour in the CASUM/ZASUM kernels for AVX512 targets
worked around a problem in the pre-AVX kernel for GEMV
sped up the thread management code on MS Windows

arm64:

fixed building of the LAPACK testsuite with Xcode 15 on Apple M1 and newer
sped up the thread management code on MS Windows
sped up SGEMM and DGEMM on Neoverse V1
sped up ?DOT on SVE-capable targets
reduced the number of targets in DYNAMIC_ARCH builds by eliminating functionally \ 
equivalent ones
included support for Apple M1 and newer targets in DYNAMIC_ARCH builds

power:

improved the SGEMM kernel for POWER10
fixed compilation with (very) old versions of gcc
fixed detection of old 32bit PPC targets in CMAKE-based builds
added autodetection of the POWERPC 7400 subtype
fixed CMAKE-based compilation for PPCG4 and PPC970 targets

loongarch64:

added and improved optimized kernels for almost all BLAS functions

Log message:
math/openblas*: more portable sed for .pc modification

The old path added \b, which is not POSIX BRE. [:space:] works better with
differing seds. It removes more than \b, but in our installs, the following
suffix variable is emtpy, anyway.

Log message:
math/openblas: Fix pkg-config file for current version.

The last update broke the library name in the installed pkg-config file
for the openblas variants. Fixing this.

Our type of library naming should be pushed upstream, or adapted to
some other scheme.
