Canonical focuses on having a single library build for each architecture in it's archive, containing all possible optimizations (LP 1702917, #4). If a separate z13 optimized library is desired it needs to be placed in a PPA - for example. I think that optimizations should be ideally addressed in the upstream code - for example with (#ifndef) approaches like HW_CAPS or with S390_ALTERNATIVE macros. Any thoughts and opinions?
