If we are doing a VPATH build and we generate the manpages,
they will be written to the build directory, and should be
deleted by ‘make distclean’; ‘make distcheck’ fails if this
is not done. However, if we are doing a build in the source
directory, the manpages might have been shipped to us and we
should *not* delete them in ‘make distclean’.
Correction to 5d3c99e562.
* man/local.mk (distclean-local-man): New rule. Delete $(dist_man_MANS)
in VPATH builds only.
(MOSTLYCLEANFILES, .x.1): Don’t use globs to decide what to delete.
