Subject: [PATCH] llvm: force `TargetOptions.UseInitArray` to `true`

The `TargetOptions` default constructor initializes all `bool`s to
`false`, yet clang defaults to setting this option to `true`.  Since
recent glibc versions on linux do not appear to support this being set
to `false`, just changing the default for now unless a use case for
making it configurable is found.
