This patch adds full support for linking SystemZ (ELF s390x) object files. Support should be generally complete: - All relocation types are supported. - Full shared library support (DYNAMIC, GOT, PLT, ifunc). - Relaxation of TLS and GOT relocations where appropriate. - Platform-specific test cases. In addition to new platform code and the obvious changes, there were a few additional changes to common code: - Add three new RelExpr members (R_GOTPLT_OFF, R_GOTPLT_PC, and R_PLT_GOTREL) needed to support certain s390x relocations. I chose not to use a platform-specific name since nothing in the definition of these relocs is actually platform-specific; it is well possible that other platforms will need the same. - A couple of tweaks to TLS relocation handling, as the particular semantics of the s390x versions differ slightly. See comments in the code. This was tested by building and testing >1500 Fedora packages, with only a handful of failures; as these also have issues when building with LLD on other architectures, they seem unrelated.
