The initial stdlib modifications for L4Re just used the linux specifics directly because they were reasonably close to L4Re's behavior. However, this breaks when Linux-specific code relies on code that is only available for the linux target, such as in #81825. Put L4Re into its own platform to avoid such breakage in the future. This uses the Linux-specific code as a starting point, which seems to be in line with other OSes with a unix-y interface such as Fuchsia.
