Fix incorrect leading dimension check for SME SGEMM direct kernel path For row-major matrices, the tight-packing condition should be k==lda (A is m×k), n==ldb (B is k×n), and n==ldc (C is m×n). The old check used m==lda and k==ldc, which prevented the SME/direct kernel from being invoked except when m==k==n (square matrices). Fixes https://github.com/OpenMathLib/OpenBLAS/issues/5794

Makefile.power: allow using power10 instructions OpenBLAS uses various power9 and power10 instructions and they fail to build with errors like in https://github.com/OpenMathLib/OpenBLAS/issues/4793. Just allow the latest ISA, it will generate the same code, but actually allow the binaries to be assembled.

Makefile.system: when Clang is used, check if gfortran is used At least on power, GCCVERSIONGT4 is checked for when gfortran is used, like at Makefile.power:59
