Patch adapted from [1]:
musl doesn't expose these sysconf values, so just use the loop
below that reads them out of sysfs coherency_line_size only
For the __pagesize bit, this is currently only used on arm64 and aborts
if __pagesize != GetRuntimePageSize -- so, as a wishful thinking solution,
have it return __pagesize.
