Add a 24x8 kernel to the skylakex dgemm implementation
Minor gains for small matrixes, but at 512x512 and above the gain
gets more significant.

skylake dgemm: Add a 16x8 kernel
The next step for the avx512 dgemm code is adding a 16x8 kernel.
In the 8x8 kernel, each FMA has a matching load (the broadcast);
in the 16x8 kernel we can reuse this load for 2 FMAs, which
in turn reduces pressure on the load ports of the CPU and gives
a nice performance boost (in the 25% range).

Fix unknown type name __WAIT_STATUS on RHEL5
With glibc 2.5 one must have #define _XOPEN_SOURCE >= 500 to use wait.
But reading glibc code this is actually needed only if stdlib.h was
included before sys/wait.h. This was the case here through
openblas_utest.h. So changing include fix compilation on RHEL5 and
should ne hurt with more recent distro.
