We don't need our own architecture macros; the standard ones will do. This patch also fixes some __x86_64__ tests to be USE_RELA tests instead, because they're not actually x86_64-specific. I've cleaned up architecture-specific code slightly so where possible all the code corresponding to a particular architecture is together. This patch also fixes a bug in LP64 DT_PLTGOT handling, which should be an error rather than falling through into DT_DEBUG! There was another #ifdef bug where we'd only report unexpected DT_ entries on MIPS. Change-Id: Id1d04e372611f641c1aa278a18e379f28af9eaf5
