[S390] Add hwcap flag for the etf3 enhancement facility
The Extended Translation Facility 3 (ETF3) added instructions which allow conversions between different unicode character maps (UTF-8, UTF-32 ...). These instructions got enhanced with a later version of the ETF3 allowing malformed multibyte chars to be recognized and reported correctly. The attached patch reserves bit 8 in the elf hwcaps vector for the enhanced version of ETF3. The bit corresponds to the stfle bits 22 and 30 and will only be set if both of the stfle bits are set.
