configure.ac: check for __builtin_cpu_supports call support
The '__builtin_cpu_supports' is a GCC's built-in function which returns a positive integer if the run-time CPU supports specified SIMD feature and returns 0 otherwise. It is required for further SSE optimization of Viterbi decoder. This change adds a new check, whether compiler supports this call. See /gcc/X86-Built-in-Functions.html at gcc.gnu.org for reference.
