elf: Add glibc-hwcaps subdirectory support to ld.so cache processing This recognizes the DL_CACHE_HWCAP_EXTENSION flag in cache entries, and picks the supported cache entry with the highest priority. The elf/tst-glibc-hwcaps-prepend-cache test documents a non-desired aspect of the current cache implementation: If the cache selects a DSO that does not exist on disk, _dl_map_object falls back to open_path, which may or may not find an alternative implementation. This is an existing limitation that also applies to the legacy hwcaps processing for ld.so.cache. Reviewed-by: Adhemerval Zanella <adhemerval.zanella@linaro.org>

S390: Add new s390 platform z16. The new IBM z16 is added to platform string array. The macro _DL_PLATFORMS_COUNT is incremented. _dl_hwcaps_subdir is extended by "z16" if HWCAP_S390_VXRS_PDE2 is set. HWCAP_S390_NNPA is not tested in _dl_hwcaps_subdirs_active as those instructions may be replaced or removed in future. tst-glibc-hwcaps.c is extended in order to test z16 via new marker5. A fatal glibc error is dumped if glibc was build with architecture level set for z16, but run on an older machine. (See dl-hwcap-check.h)
