 Add the libstd-modifications needed for the L4Re target

This commit adds the needed modifications to compile the std crate for the L4 Runtime environment (L4Re).

A target for the L4Re was introduced in commit: c151220a84e40b65e45308cc0f3bbea4466d3acf

In many aspects implementations for linux also apply for the L4Re microkernel.

Some uncommon characteristics had to be resolved:
 * L4Re has no network funktionality
 * L4Re has a maximum stacksize of 1Mb for threads
 * L4Re has no uid or gid
