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?
