openssl/crypto/s390xcap.c
Richard Levitte 5768804d5a crypto/s390xcap.c: Add guards around the GETAUXVAL checks 
HWCAP_S390_VX is missing on SUSE Linux Enterprise Server 12 SP1, so we
add a guard that checks the present of that macro.  While we're at it,
we do the same with HWCAP_S390_STFLE, for consistency.
