Avoid compile-time CPU-detection (boo#1100677)
the docs in GotoBLAS_02QuickInstall.txt say
3. Specifying target architecture
If you need library for different architecture, you can use TARGET
option. You can find current available options in top of getarch.c.
For example, if you need library for Intel core2 architecture,
you'll find FORCE_CORE2 option in getarch.c. Therefore you can
specify TARGET=CORE2 (get rid of FORCE_) with make.
$shell> make TARGET=CORE2
This is rather unspecific, but my tests show it helps to get reproducible binaries and compilation still happens with -DDYNAMIC_ARCH -march=skylake-avx512

- 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

50 threads by default.
* The output of openblas_get_config() now contains the version
number.

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).

known-threadsafe (but non-default)
USE_SIMPLE_THREADED_LEVEL3 option.

compile/link
* steps to facilitate setting platform-specific linker flags.

be supported via the slower PRESCOTT kernels when this option
is not set)
