- Update to version 0.3.4
  common:
    * The new, experimental thread-local memory allocation had
      inadvertently been left enabled for gmake builds in 0.3.3
      despite the announcement. It is now disabled by default,
      and single-threaded builds will keep using the old
      allocator even if the USE_TLS option is turned on.
    * OpenBLAS will now provide enough buffer space for at least
      50 threads by default.
    * The output of openblas_get_config() now contains the version
      number.
    * A serious thread safety bug in GEMV operation with small M and
      large N size has been fixed.
    * The code will now automatically call blas_thread_init after
      a fork if needed before handling a call to
      openblas_set_num_threads
    * Accesses to parallelized level3 functions from multiple
      callers are now serialized to avoid thread races
      (unless using OpenMP).
    * This should provide better performance than the
      known-threadsafe (but non-default)
      USE_SIMPLE_THREADED_LEVEL3 option.
    * When building LAPACK with gfortran, -frecursive is now
      (again) enabled by default to ensure correct behaviour.
    * The OpenBLAS version cblas.h now supports both CBLAS_ORDER
      and CBLAS_LAYOUT as the name of the matrix row/column order
      option.
    * Externally set LDFLAGS are now passed through to the final
      compile/link
    * steps to facilitate setting platform-specific linker flags.

option.
* Externally set LDFLAGS are now passed through to the final
compile/link
* steps to facilitate setting platform-specific linker flags.
* A potential race condition during the build of LAPACK
(that would usually manifest itself as a failure to build
TESTING/MATGEN) has been fixed.
* xHEMV has been changed to stay single-threaded for small
input sizes where the overhead of multithreading exceeds
any possible gains
* CSWAP and ZSWAP have been limited to a single thread
except on ARMV8 or ThunderX hardware with sizable input.
* Linker flags for the PGI compiler have been updated
* Behaviour of AXPY with zero increments is now handled
in the C interface, correcting the result on at least
Intel Atom.
* The result matrix from calling SGELSS with an all-zero
input matrix is now zeroed completely.
x86_64:
* Autodetection of AMD Ryzen2 has been fixed (again).
* CMAKE builds now support labeling of an INTERFACE64=1
build of the library with the _64 suffix.
* AVX512 version of DGEMM has been added and the
AVX512 SGEMM kernel has been sped up by rewriting
with C intrinsics
* Fixed compilation on RHEL5/CENTOS5
(issue with typename __WAIT_STATUS)
armv8:
* DYNAMic_ARCH support is now available for 64bit ARM
* cross-compiling for ARMV8 under iOS now works.
* cpu-specific code has been rearranged to make better
use of both hardware commonalities and model-specific
compiler optimizations.
* XGENE1 has been removed as a TARGET, superseded by the
improved generic ARMV8 support.
armv7:
* Older assembly mnemonics have been converted to UAL
form to allow building with clang 7.0
