[ Simon Chopin ]
* d/rules: use configure options for dfltcc instead of hardcoding
the CFLAGS
* d/p/lp1932010-ibm-z-add-vectorized-crc32-implementation.patch
ported from zlib-ng #912, adding a vectorized implementation
of CRC32 on s390x architectures based on kernel code. LP: #1932010
[ Michael Hudson-Doyle ]
* d/p/lp1932010-ibm-z-add-vectorized-crc32-implementation.patch: adjust to
