common: - drastically reduced the stack size requirements for running the LAPACK testsuite (Reference-LAPACK PR 553) - fixed spurious test failures in the LAPACK testsuite (Reference-LAPACK PR 564) - expressly setting DYNAMIC_ARCH=0 no longer enables dynamic_arch mode - improved performance of xGER, xSPR, xSPR2, xSYR, xSYR2, xTRSV, SGEMV_N and DGEMV_N, for small input sizes and consecutive arguments - improved performance of xGETRF, xPORTF and xPOTRI for small input sizes by disabling multithreading - fixed installing with BSD versions of the "install" utility

RISCV: - fixed the implementation of xIMIN - improved the performance of DSDOT - fixed linking of the tests on C910V with current vendor gcc

POWER: - fixed SBGEMM computation for some odd value inputs - fixed compilation for PPCG4, PPC970, POWER3, POWER4 and POWER5

x86_64: - improved performance of SGEMV_N and SGEMV_T for small N on AVX512-capable cpus - worked around a miscompilation of ZGEMM/ZTRMM on Sandybridge with old gcc versions - fixed compilation with MS Visual Studio versions older than 2017 - fixed macro name collision with winnt.h from the latest Win10 SDK - added cpu type autodetection for Intel Ice Lake SP - fixed cpu type autodetection for Intel Tiger Lake - added cpu type autodetection for recent Centaur/Zhaoxin models - fixed compilation with musl libc

ARM64: - fixed compilation with gcc/gfortran on the Apple M1 - fixed linking of the tests on FreeBSD - fixed missing restore of a register in the recently rewritten DNRM2 kernel for ThunderX2 and Neoverse N1 that could cause spurious failures in e.g. DGEEV - added compiler optimization flags for the EMAG8180 - added initial support for Cortex A55

ARM: - fixed linking of the tests on FreeBSD
