[Bug 1932010] Re: [21.10 FEAT] zlib CRC32 optimization for s390x

[Michael Hudson-Doyle]

At a very quick glance, Simon's patch looks a bit closer to the pull
request than the one in comment #4, so if you could test that soon that
would be good.

Simon, aside from debian/patches/lp1932010-ibm-z-add-vectorized-
crc32-implementation.patch which I'm not sure I'm competent to review
beyond seeing how it compares to the pull request, your patch looks
mostly fine but it seems you've duplicated the definition of CONFIGURE_*
in debian/rules? You probably don't want to do that?
