As far as I can see, glibc only supports reading the cache line size for
few architectures, probably fewer than those that provide the sysfs file.
I don't see a generic way to query this on mips and the return code
should be the same as sysconf on uclibc/glibc, so this function makes
sense. It should probably be made static though...
