newlib: libm: move manual into top-level build This doesn't migrate all the docs, just the libm's manual (pdf/info). This is to show the basic form of migrating the chew files.

newlib: move man page generation into top-level build This allows building the libc & libm pages in parallel, and drops the duplication in the subdirs with the chew/chapter settings. The unused rules in Makefile.shared are left in place to minimize noise in the change.

newlib: fix mkdoc dependencies Make sure we depend on the right name of mkdoc all the time, and that the rules that need it (e.g. .def files) depend on it. Reported-by: Jon Turney <jon.turney@dronecode.org.uk>

newlib: libm: merge build up a directory Convert all the libm/ subdir makes into the top-level Makefile. This allows us to build all of libm from the top Makefile without using any recursive make calls. This is faster and avoids the funky lib.a logic where we unpack subdir archives to repack into a single libm.a. The machine override logic is maintained though by way of Makefile include ordering, and source file accumulation in libm_a_SOURCES. One thing to note is that this will require GNU Make because of: libm_a_CFLAGS = ... $(libm_a_CFLAGS_$(subst /,_,$(@D))) This was the only way I could find to supporting per-dir compiler settings, and I couldn't find a POSIX compatible way of transforming the variable content. I don't think this is a big deal as other Makefiles in the tree are using GNU Make-specific syntax, but I call this out as it's the only one so far in the new automake code that I've been writing. Automake doesn't provide precise control over the output object names (by design). This is fine by default as we get consistent names in all the subdirs: libm_a-<source>.o. But this relies on using the same set of compiler flags for all objects. We currently compile libm/common/ with different optimizations than the rest. If we want to compile objects differently, we can create an intermediate archive with the subset of objects with unique flags, and then add those objects to the main archive. But Automake will use a different prefix for the objects, and thus we can't rely on ordering to override. But if we leverage $@, we can turn Automake's CFLAGS into a multiplex on a per-dir (and even per-file if we wanted) basis. Unfortunately, since $@ contains /, Automake complains it's an invalid name. While GNU Make supports this, it's a POSIX extension, so Automake flags it. Using $(subst) avoids the Automake warning to get a POSIX compliant name, albeit with a GNU Make extension.

## The order of includes is important for two reasons:
## * The integrated documentation (chapter ordering).
## * Object overridding -- machine dir must come last.
## Do not change the order without considering the doc impact.

newlib: libm: integrate tests subdir Integrate the old libm/test/ subdir into the main build. It hasn't been used in a long time causing the code to rot a bit. I've fixed some of those, but it still fails for many ports, so it's disabled by default. People who want to take a closer look can run: $ make libm/test/test
