meson: sphinx-build

For now, sphinx is run on every invocation of make.  The previous mechanism
using $(wildcard) is not reproducible in Meson and was also brittle; for
example some .rst.inc files were left out.  The next patch will introduce
a Sphinx extension to emit a depfile.

-# Support for building multiple output files by atomically executing
-# a single rule which depends on several input files (so the rule
-# will be executed exactly once, not once per output file, and
-# not multiple times in parallel.) For more explanation see:
-# https://www.cmcrossroads.com/article/atomic-rules-gnu-make
-
-# Given a space-separated list of filenames, create the name of
-# a 'sentinel' file to use to indicate that they have been built.
-# We use fixed text on the end to avoid accidentally triggering
-# automatic pattern rules, and . on the start to make the file
-# not show up in ls output.
-sentinel = .$(subst $(SPACE),_,$(subst /,_,$1)).sentinel.
-
-# Define an atomic rule that builds multiple outputs from multiple inputs.
-# To use:
-#    $(call atomic,out1 out2 ...,in1 in2 ...)
-#    <TAB>rule to do the operation
-#
-# Make 4.3 will have native support for this, and you would be able
-# to instead write:
-#    out1 out2 ... &: in1 in2 ...
-#    <TAB>rule to do the operation
-#
-# The way this works is that it creates a make rule
-# "out1 out2 ... : sentinel-file ; @:" which says that the sentinel
-# depends on the dependencies, and the rule to do that is "do nothing".
-# Then we have a rule
-# "sentinel-file : in1 in2 ..."
-# whose commands start with "touch sentinel-file" and then continue
-# with the rule text provided by the user of this 'atomic' function.
-# The foreach... is there to delete the sentinel file if any of the
-# output files don't exist, so that we correctly rebuild in that situation.
