With coreutils-8.22, the arch manpage is completely empty (ie, has zero length): # ls -l /usr/share/man/man1/arch.1 -rw-r--r-- 1 root root 0 Apr 12 21:00 /usr/share/man/man1/arch.1 This is caused by a combination of the manpage being missing from coreutils-8.22-man.tar.xz and a snippet in src_prepare that touches all manpages to prevent the build system from regenerating them: # tar -tvf /var/lib/portage/distfiles/coreutils-8.22-man.tar.xz | grep -c arch 0 Snippet from src_prepare: # Since we've patched many .c files, the make process will try to # re-build the manpages by running `./bin --help`. When doing a # cross-compile, we can't do that since 'bin' isn't a native bin. # Also, it's not like we changed the usage on any of these things, # so let's just update the timestamps and skip the help2man step. set -- man/*.x touch ${@/%x/1} Since coreutils-8.22.tar.xz contains man/arch.x, this snippet creates an empty man/arch.1, preventing the build system from generating the manpage, and thus resulting in the empty manpage being propagated on to the install.
i've regenerated the man page tarball to include the arch(1) man page
