[Bug 1982583] Re: zlib CRC32 optimization for s390x works only in a static library

[Frank Heimes]

** Description changed:

+ 'zlib CRC32 optimization for s390x works only in a static library'
+ 
  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.

** Summary changed:

- zlib CRC32 optimization for s390x works only in a static library
+ Fix for zlib CRC32 optimization for s390x
