Yes, because the build won't be reproduceable otherwise. Systems with
openssl-devel will use that implementation if they build the SRPM,
whereas systems without it would get the mhash version.
This could be worked around by setting environment variable
ac_cv_search_MD5_Init to "no" before running %configure so that MD5_Init
wasn't found and it would then look for and find mhash_init. However,
that would then result in a dependency on libmhash.so.2, which lives in
%{_libdir} rather than /lib and hence breaks Alexander's aim of being
able to use mbuffer with /usr not mounted.
