FYI This reminds me of something. I was forwarded a complaint that
the RISC-V ABI was violating the Filesystem Hierarchy Standard (FHS),
which specifies that libraries are only allowed to be in /lib and
/lib<qual>. The complaint was that /lib64/lp64d doesn't follow this
pattern, and hence is a violation of this standard. However, the
standard doesn't clearly state that <qual> can't contain a slash. The
person who complained insisted that it was implied. It wasn't clear
to me what to do with the complaint. Changing the ABI now would be
rather disruptive and undesirable, and I also don't know how important
the FHS standard is, or whether this interpretation is correct.
