This separates ET_DYN ASLR from mmap ASLR, as already done on s390. The
various architectures that are already randomizing mmap (arm, arm64, mips,
powerpc, s390, and x86), have their various forms of arch_mmap_rnd()
made available via the new CONFIG_ARCH_HAS_ELF_RANDOMIZE. For these
architectures,
When an architecture fully supports randomizing the ELF load location, the
arch_mmap_rnd() function becomes available. Rename and expose these functions
where they exist. Introduces CONFIG_ARCH_HAS_ELF_RANDOMIZE.
