man: Kill off MANSUBDIRs

Three architecture dependent manuals are installed to MANSUBDIRs,
creating at least two empty manual page directories on everyone's
boxxen. Move those manuals to their canonical area, enhancing clarity,
grepability, removing useless inodes, and increasing consistency with
the rest of the architecture dependent manuals which are unconditionally
installed, and noted at the top of the rendered manual.
