x86_64: prevent GCC and Clang from generating FMAs in cscal/zscal.

Bart Oldeman e7e3aa2948 x86_64: prevent GCC and Clang from generating FMAs in cscal/zscal.
If e.g. -march=haswell is set in CFLAGS, GCC generates FMAs by default, which
is inconsistent with the microkernels, none of which use FMAs. These
inconsistencies cause a few failures in the LAPACK testcases, where
eigenvalue results with/without eigenvectors are compared.

Moreover using FMAs for multiplication of complex numbers can give surprising
results, see 22aa81f for more information.

This uses the same syntax as used in 22aa81f for zarch (s390x).

Honglin Zhu b00d5b9746 New sbgemm implementation for Neoverse N2
1. Use UZP instructions but not gather load and scatter store instructions to get lower latency.
    2. Padding k to a power of 4.

Rajalakshmi Srinivasaraghavan a612e78a97 POWER: Fix complex dot function failures
There are some test failures in complex dot functions when compiling with gcc12.
The machine constraints used now do not update all the four elements in the
expected result array. Fixing this with a reduced level of optimization.
This is not changing any performance numbers but will be converted to C code in future.

POWER10: Fix multithreading check when USE_THREAD=0
This patch fixes an issue when OpenBLAS is compiled for TARGET=POWER10
and the flag USE_THREAD is set to 0.

The function `num_cpu_avail` is only available when USE_THREAD=1,
so SMP is defined.
