87b3d9054f Fix regression SAXPY when compiler with OpenXL compiler. 
SAXPY built with OpenXL regresses when compared to SAXPY
built with gcc. OpenXL compiler doesn't know that the
SAXPY inner kernel assembly is a 64 element loop and
to it the remainder loop is the main loop. It vectorizes
and interleaves the remainder to be a 48 elements per
iteration loop. With a max of 63 iterations, a 48 element
loop is mostly not going to get executed, so the 1 element
scalar loop that is the remainder after that is probably
mostly what gets executed.

This can be fixed by adding a pragma, loop interleave_count(2)
which will result in 8 element loop.

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.

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.
