rtld-elf has some vestigial support for building as a static executable. r45501 introduced a partial implementation with a prescient note that it "might never be enabled." r153515 introduced ELF symbol versioning support, and removed part of the unused build infrastructure for static rtld. GNU ld populates rela relocation addends and GOT entries with the same values, and rtld's run-time dynamic executable check relied on this. Alternate toolchains may not populate the GOT entries, which caused RTLD_IS_DYNAMIC to return false. Simplify rtld by just removing the unused check. If we want to restore static rtld support later on we ought to introduce a build-time #ifdef flag.
