[Libguestfs] [libnbd PATCH 0/2] Drop generated file from git

Rich recently patched things to generate one man page per function
rather than libnbd-api.3 (nice), but in doing so got stumped by a
problem with a fresh git clone (automake fails for any 'include'
directive that does not already exist).  I've figured out how to hack
around it, but the hack requires GNU make.  We already use GNU make
constructs elsewhere (such as $(wildcard)), but while existing uses
are out of laziness and can probably be rewritten in portable make if
someone complained, this patch series cements our dependency on GNU
make (I don't know of any way to fix this problem for non-GNU make).
Hence I'm posting this for review, even though I think it's good to
go.

[Libguestfs] [libnbd PATCH 1/2] docs: Simplify generated docs/Makefile.inc

Rather than using Automake conditionals and one rule per file, make
the generated file merely contain a list of function names, and do the
bulk of the work in the main Makefile.am using GNU make pattern
substitutions.  This is a prerequisite to figuring out how to remove
dosc/Makefile.inc from git while still keeping automake happy and
still working on the correct set of files.

[Libguestfs] [libnbd PATCH 2/2] docs: Drop docs/Makefile.inc from git

Automake insists that any file present in a Makefile.am 'include' must
be present, but it has no idea about the GNU make extension
'sinclude'.  Use this to our advantage: as long as Makefile.inc has
nothing other than variable modifications (done in the previous
patch), and our rules properly generate it when needed (thanks to
generator_built), then running 'make' will still build all the right
man pages, and 'make dist' will still distribute all the right
generated .pod files for the sake of someone building the tarball
without OCaml, all without having to keep a generated file in git.
