Add run-one-test convenience target and makefile help text

Browse Source 
Adds "make test" for re-running just one test.  Also adds
"make help" for help with our Makefile targets, and adds a
mini-help when you just run "make".

This is the file that gets printed when the user runs "make help",
starting just after the "help-starts-here" line.
help-starts-here
all
The usual default; builds everything but doesn't run the
tests.
check (or tests)
Runs the standard set of tests.
test
Runs one test. Use like this:
make test t=wcsmbs/test-wcsnlen
Note that this will rebuild the test if needed, but will not
rebuild what "make all" would have rebuilt.
--
Other useful hints:
builddir$ rm testroot.pristine/install.stamp
Forces the testroot to be reinstalled the next time you run
the testsuite (or just rm -rf testroot.pristine)
