This patch fixes cpuid on arm when /proc/cpuinfo identifies the cpu by Processor rather than model name.

On my system (Samsung Chromebook XE303C12 / Exynos5 / Cortex A15 with Ubuntu 12.04), cpuinfo has the following output:

user@chrubuntu:~/dev/OpenBLAS$ cat /proc/cpuinfo
Processor       : ARMv7 Processor rev 4 (v7l)
processor       : 0
BogoMIPS        : 1694.10

processor       : 1
BogoMIPS        : 1694.10

Features        : swp half thumb fastmult vfp edsp thumbee neon vfpv3 tls vfpv4 idiva idivt
CPU implementer : 0x41
CPU architecture: 7
CPU variant     : 0x0
CPU part        : 0xc0f
CPU revision    : 4

Hardware        : SAMSUNG EXYNOS5 (Flattened Device Tree)
Revision        : 0000
Serial          : 0000000000000000

(based on some limited google searches, I believe that some other ARM systems have such output, but I do not know what is the general convention)
