This was used before switching to automake to allow easy tweaking
of optimization and debugging settings from the command line during
testing. Reenable.

So far, the mqd_t type returned a pointer to an allocated
area under the hood. The mutex and event objects attached
to the message queue were implemented as inheritable types.
As unfortunate side effect the HANDLEs to these objects
were inherited by exec'd child processes, even though all
other message queue properties are not inherted, per POSIX.
Fix this by converting an mqd_t to a descriptor, and create a
matching fhandler_mqueue object to handle various aspects of
the message queues inside the fhandler. Especially, create the
IPC objects as non-inheritable and duplicate the HANDLEs as
part of the fixup_after_fork mechanism.
Drop using mmap and create the memory map with NT functions.
This allows to control duplication of handle and mapping in the
forked child process, without the requirement to regenerate the
map in the same spot. It also allows to dup() the descriptor,
as on Linux, albeit this isn't implemented yet.
This patch is the first cut. There's a bit more to do, like
moving more functionality from the POSIX functions into the
fhandler and making sure the mqd_t type can't be used in other
descriptor-related functions willy-nilly.

Converting to automake dropped the former, handwritten tags/ctags
target. This leads to a couple of problems:
- For no good reason the tags file gets written to the builddir
instead of to the srcdir where it's needed.
- `make tags' requires etags to exist, rather than checking if it
exists and skipping it.
- Adding the extra ctags arguments to AM_CTAGSFLAGS still results
in a shortened tags file.
(Temporary?) solution: Revert the old tags/ctags rules and silence
the automake warnings.

Specify toollibdir and toolincludedir in terms of tooldir, so the
install location is correct if tooldir is the default
($(exec_prefix)/$(target_alias)), or explicitly specified on the 'make'
command line.
v2:
* Include tzmap.h in BUILT_SOURCES
* Make per-file flags appear after user-supplied CXXFLAGS, so they can
override optimization level.
* Correct .o files used to define symbols exported by libm.a
* Drop gcrt0.o mistakenly included in libgmon.a
* Add missing line continuations in GMON_FILES value
v3:
* use per-file flags for .c compilation
* override C{XX,}FLAGS, as they are set on the command line by top-level make
v4:
* Drop -Wno-error=write-strings from path_testsuite CXXFLAGS
v5:
* Update for changes in master
- Add -fno-threadsafe-statics to CXX flags
- Add hypotl.cc
- Remove fenv.cc (in favour of newlib), add fenv.c stub
- Add proc.5 manpage rules
