When building the `OSLog` module, look for a variable named
`osLogStringSectionName`. It must have a string literal as its
initializer, which provides the section name where the log strings
should be emitted. The `OSLog` module should contain something like
this:
let osLogStringSectionName = "__TEXT,__logit"
When not present, the compiler will default to
`__TEXT,__oslogstring,cstring_literals`, which was previously the
hardcoded section name. Now, OSLog can customize the name.
