Propagate SWITCH_RATIO to DYNAMIC_ARCH builds

ec334e69dc Use SVE kernel for SGEMM/DGEMM on Arm(R) Neoverse(TM) V1 
This re-spins #3869 with some additional copy unrolling which helps maintain SYRK performance.

After #3868, the SVE kernels represent a pretty good boost.

This re-uses ARMV8SVE as a base and I'm going to incrementally move everything to use ARMV8SVE in additional patches (as well as fix up anything that's not already in ARMV8SVE).

32f2fafde7 Propagate SWITCH_RATIO to DYNAMIC_ARCH builds 
Previously dynamic builds were either using the default SWITCH_RATIO
or one from the higher level architecture; this patch ensures the
dynamic builds can use this parameter as well.

Remove prefetches from SVE kernels

1361229291 Remove prefetches from SVE kernels 
This is a precursor to enabling the SVE kernels for Arm(R) Neoverse(TM)
V1 which has 256-bit SVE. Testing revealed that the SVE kernel was
actually worse in some cases than the existing kernel which seemed odd -
removing these prefetches the underlying architecture seems to do a better job

5ceca1a4d8 Add sscal.c + microkernels for Haswell, Zen, Skylake and newer. 
Unlike [dcz]scal, sscal still used the original GotoBLAS SSE code from scal_sse.S.
This code follows dscal as closely as possible, except for the inc_x > 1 code
for which a plain C loop is used much like the one in cscal.c, instead of an
adaptation of the SSE2 asm code of dscal.c (I tried but the performance wasn't
better than the plain C loop).

5c3169ecd8 dscal: use ymm registers in Haswell microkernel 
Using 256-bit registers in dscal makes this microkernel consistent with
cscal and zscal, and generally doubles performance if the vector fits in
L1 cache.
