David Rheinsberg bc88508487 build: improve make man
This improves `make man` in the following ways:

  * The recently added `osbuild-manifest.5` man-page is now generated
    as well.

  * The target now honors `SRCDIR` and `BUILDDIR` variables.

  * Any newly added man-page is now automatically picked up and
    generated as well.

  * The output directory structure now mirrors the input directory
    structure.

# Maintenance Helpers
#
# This makefile contains targets used for development, as well as helpers to
# aid automatization of maintenance. Unless a target is documented in
# `make help`, it is not supported and is only meant to be used by developers
# to aid their daily development work.
#
# All supported targets honor the `SRCDIR` variable to find the source-tree.
# For most unsupported targets, you are expected to have the source-tree as
# your working directory. To specify a different source-tree, simply override
# the variable via `SRCDIR=<path>` on the commandline. While you can also
# override `BUILDDIR`, you are usually expected to have the build output
# directory as working directory.
#
BUILDDIR ?= .
SRCDIR ?= .

#
# Automatic Variables
#
# This section contains a bunch of automatic variables used all over the place.
# They mostly try to fetch information from the repository sources to avoid
# hard-coding them in this makefile.
#
# Most of the variables here are pre-fetched so they will only ever be
# evaluated once. This, however, means they are always executed regardless of
# which target is run.
#
# VERSION:
# This evaluates the `version` field of `setup.py`. Therefore, it will
# be set to the latest version number of this repository without any
# prefix (just a plain number).
#
# COMMIT:
# This evaluates to the latest git commit sha. This will not work if
# the source is not a git checkout. Hence, this variable is not
# pre-fetched but evaluated at time of use.
#
VERSION := $(shell (cd "$(SRCDIR)" && python3 setup.py --version))
COMMIT = $(shell (cd "$(SRCDIR)" && git rev-parse HEAD))
#
# Generic Targets
#
# The following is a set of generic targets used across the makefile. The
# following targets are defined:
#
# help
# This target prints all supported targets. It is meant as
# documentation of targets we support and might use outside of this
# repository.
# This is also the default target.
#
# $(BUILDDIR)/
# $(BUILDDIR)/%/
# This target simply creates the specified directory. It is limited to
# the build-dir as a safety measure. Note that this requires you to use
# a trailing slash after the directory to not mix it up with regular
# files. Lastly, you mostly want this as order-only dependency, since
# timestamps on directories do not affect their content.

# ./rpmbuild, using rpmbuild's usual directory structure.
