    perf: enable man pages for 'help' functionality
    
    When using 'perf help <subcommand>', it can't find 'man' command and pages for
    perf.
    The perf man pages depends on the xmlto-native and asciidoc-native, so we just
    need to add the two packages to the DEPENDS variable and add 'man'to
    RDEPENDS_perf-doc.
