to fix linking problems with (at least) the AMD version of flang that creates dependencies on more than just the fortran runtime.

This patch is to enable benchtest for half precision gemm
when BUILD_HALF is set during make.

[description]: when the matrix size goes higher than 5800 during the cpotrf test, error info, such as "Potrf info = 5679", will be returned on ARM64 and x86 machines. Uplo = L & F.
[solution]: changed the func for building the matrix so that the complex Hermitian matrix can stay positive definite during the computation.

2.Fixed some errors

Fix potential index overflows at large matrix sizes in the benchmark codes

Update benchmark statistical time function

The function gettimeofday does not count the time，when testing the axpy small data volume use case.
Use the function clock_gettime to replace the gettimeofday function to count the time.
