Don't overwrite blas_thread_buffer if already set
...
After a fork it is possible that blas_thread_buffer has already
allocated memory buffers: goto_set_num_threads does allocate those
already and it may be called by num_cpu_avail in case the OpenBLAS
NUM_THREADS differ from the OMP num threads.
This leads to a memory leak which can cause subsequent execution of BLAS
kernels to fail.
Fixes #2993

POWER10: Fix ld version detection
...
LDVERSIONGTEQ35 needs to escape the '>' character.
LDVERSIONGTEQ35 is checking the system ld version which may be different
to the toolchain being used to compile OpenBLAS. We don't have a path
to the linker in our Makefiles, so (ab)use gcc -Wl,--version to get the
version of ld in our toolchain.
