It works only in implicit rules (or with GNU Make, but not with
Solaris Make).

* examples/c/reccalc/local.mk, examples/d/local.mk,
* examples/java/local.mk: Don't use $< in non implicit rules.
Commit 112ccb5ed7 moved the skeletons
from dist_pkgdata_DATA to dist_skeletons_DATA, hence broke the dependencies.
* Makefile.am (dependencies): New.
Use it where appropriate.
Convert some of the READMEs to Markdown, which is now more common, and
nicely displayed in some git hosting services.
Add missing READMEs and Makefiles. Generate XML, HTML and Dot files. Be
sure to ship the test files. Complete CLEANFILES to remove all generated
files.
* examples/calc++: Move into...
* examples/c++: here.
* examples/mfcalc, examples/rpcalc: Move into...
* examples/c: here.
* examples/README.md, examples/c++/calc++/Makefile, examples/c/local.mk,
* examples/c/mfcalc/Makefile, examples/c/rpcalc/Makefile,
* examples/d/README.md, examples/java/README.md:
New files.
* examples/test (medir): Be robust to deeper directory nesting.
