Remove unused dl-procinfo.h
Remove unused _dl_hwcap_string defines. As a result many dl-procinfo.h headers can be removed. This also removes target specific _dl_procinfo implementations which only printed HWCAP strings using dl_hwcap_string. Reviewed-by: Adhemerval Zanella <adhemerval.zanella@linaro.org>
