Title:
  zlib CRC32 optimization for s390x works only in a static library

Status in zlib package in Ubuntu:
  New

Bug description:
  I've discovered two issues in lp1932010-ibm-z-add-vectorized-
  crc32-implementation.patch:

  1) s390_crc32_vx() signature mismatch, resulting in a warning.
  2) -DS390_CRC32_VX is not added to SFLAGS, resulting in vectorization being enabled only in the static library.

  I've attached the updated patch.
